[NODEBB] CSS Style Sheets SelectBox

phenomlab

@DownPW after looking at the code on your site, I’d recommend

/* this is a listener to listen for changes on the dropdown */
$(window).on('action:ajaxify.end', function (data) {
        var isDefined = localStorage.getItem("s1"); 
        if (isDefined) {
            setStyleSource ("s1", isDefined);
    }
    else {
        setStyleSource ("s1", selected);    
    }
document.getElementById("mySelect").addEventListener("change", function(){
    var selected = this.options[this.selectedIndex].value; /* the option chosen */
        setStyleSource ("s1", selected);    
    localStorage.setItem("s1", selected); 
});
});

This will

a) Save the chosen theme from the select box, and place it in localStorage
b) On load, it will check the the existence of any setting, and apply that if it does exist
c) If no setting is defined, the default theme will be served

You also need to change your HTML code so that you do not use relative paths, but static ones as below example

<label>Choose a theme</label>
<link href="https://mysite.com/assets/client.css?v=e02phpkima0" rel="stylesheet" type="text/css" title="s1" id="s1"/>

<link href="https://mysite.com/assets/customcss/aqua.css?version=1" rel="stylesheet" type="text/css" title="aqua" id="aqua"/>
<link href="https://mysite.com/assets/customcss/solary.css?version=1" rel="stylesheet" type="text/css" title="solary" id="solary"/>
<link href="https://mysite.com/assets/customcss/EVA.01-Purple_Green.css?version=1" rel="stylesheet" type="text/css" title="EVA.01-Purple_Green.css" id="EVA.01-Purple_Green"/>

<select id="mySelect" onchange="setStyleSource ('s1', this.options[this.selectedIndex].value)">

  <option value="default.css">Default</option>
  <option value="https://mysite.com/assets/customcss/aqua.css?v=e02phpkima0">aqua</option>
  <option value="https://mysite.com/assets/customcss/solary.css?v=e02phpkima0">solary</option>
  <option value="https://mysite.com/assets/customcss/EVA.01-Purple_Green.css?v=e02phpkima0">EVA.01-Purple_Green.css</option>
</select>

I’ve set this on your site, and validated.

@DownPW This should be working on both mobile and PC/laptop now. The JS was in fact failing to load properly because the variable of selected was not set. Based on this, we need to set the variable if it’s unset to stop the JS from crashing out

// the function which changes the src 
// If "selected" is not set on page load, we'll assume the default 
if (!selected) {
var selected = "https://mysite.com/assets/client.css";
}
function setStyleSource (linkID, sourceLoc) {
  var theLink = document.getElementById(linkID);
  theLink.href = sourceLoc;
}


// this is a listener to listen for changes on the dropdown 
 $(window).on('action:ajaxify.end', function (data) {
        var isDefined = localStorage.getItem("s1"); 
        if (isDefined) {
            setStyleSource ("s1", isDefined);
    }
    else {
        setStyleSource ("s1", selected);    
    }
document.getElementById("mySelect").addEventListener("change", function(){
    var selected = this.options[this.selectedIndex].value; 
         setStyleSource ("s1", selected);    
    localStorage.setItem("s1", selected); 
});
});

There is also an issue with setSource not being defined when the JS fires. To resolve this, I added the below into the widget code

<script>
function setStyleSource (linkID, sourceLoc) {
  var theLink = document.getElementById(linkID);
  theLink.href = sourceLoc;
}
</script>

Having tested, it’s working fine on Smartphone, Tablet, PC, and laptop

The one thing I did notice is that the backgrounds do not appear on mobile devices. Looking at the CSS, it appears these will only fire if the screen size is a minimum of 1281px

/* Desktop */
@media (min-width: 1281px) {
    body {
        background: url(https://i.imgur.com/I5AAeU4.png) no-repeat center center fixed; /*Background01*/
        -webkit-background-size: cover;
        -moz-background-size: cover;
        -o-background-size: cover;
        background-size: cover;
    }
}

Not sure if this is intended or not ? I’ll leave that part up to you to decide

DownPW

Many thanks.

Very strange thing:

When I activate the widget with the select box, I have this strange bug which is already fixed in my CUSTOM CSS by default but which does not work.
alt text

.topic-list-header {
    position: sticky;
    top: 50px;
    background-color: #11ffee00;
    z-index: 1000;
    padding-top: 10px;
    padding-bottom: 10px;
    margin-bottom: 10px;
    border-top: 1px solid #11ffee00;
    border-bottom: 1px solid #11ffee00;
}

When I deactivate the widget, the bug disappears :

And when I add any others widgets, the forum loads endlessly :

it’s unfortunate

Other bug when i activate the widget

Witout widgets, it’s normal :

phenomlab

@downpw This is being caused by the CSS you have set

.topic-list-header {
    position: -webkit-sticky;
    position: sticky;
    top: 50px;
    background-color: #fff;
    z-index: 1000;
    padding-top: 10px;
    padding-bottom: 10px;
    margin-bottom: 10px;
    border-top: 1px solid #eee;
    border-bottom: 1px solid #eee;
}

The topic list header in dark mode will work as there is no background, and the color set matches. However, the only way to get this to work in light mode is to set background-color: transparent; but that also means as the list of threads grows and you scroll, you’ll be able to see through the panel.

EDIT

I just set (in aqua.css via front-end) the below

.btn-default {
    color: black !important;
    background-color: aqua !important;
    border-color: black !important;
    box-shadow: 0px 0px 8px aqua !important;
}

This works fine. When you change to Dark Mode, the style is no longer being overwritten

phenomlab

@DownPW the dropdown selector will now populate the correct value when selecting the theme and reloading. New code here

$(window).on('action:ajaxify.end', function(data) {
    var isDefined = localStorage.getItem("s1");
    var isDefinedLabel = localStorage.getItem("sLabel");
    if (isDefined) {
        setStyleSource("s1", isDefined);
    } else {
        setStyleSource("s1", selected);
    }
    if (isDefinedLabel) {
        $('#mySelect').val(isDefined).change();
    } else {

    }
    document.getElementById("mySelect").addEventListener("change", function() {
        var selected = this.options[this.selectedIndex].value;
        var selectedLabel = this.options[this.selectedIndex].text;
        setStyleSource("s1", selected);
        localStorage.setItem("s1", selected);
        localStorage.setItem("sLabel", selectedLabel);
    });
});

phenomlab

@DownPW As discussed via chat, if dark mode is selected, the themes should be stripped to prevent CSS conflicts. You can do that by using this code snippet

$(window).on('action:ajaxify.end', function(data) {
    var isDefined = localStorage.getItem("s1");
    var isDefinedLabel = localStorage.getItem("sLabel");
    if (isDefined) {
        setStyleSource("s1", isDefined);
    } else {
        setStyleSource("s1", selected);
    }
    if (isDefinedLabel) {
        $('#mySelect').val(isDefined).change();
    } else {

    }
    var isDark = localStorage.getItem('user:theme');
    if (isDark) {
        console.log("Dark mode is active");
                setStyleSource("s1", "");
                $('#mySelect').hide();
    }
    document.getElementById("mySelect").addEventListener("change", function() {
        var selected = this.options[this.selectedIndex].value;
        var selectedLabel = this.options[this.selectedIndex].text;
        setStyleSource("s1", selected);
        localStorage.setItem("s1", selected);
        localStorage.setItem("sLabel", selectedLabel);
    });
});

@DownPW After we’d discussed this further, plus your ideal situation of having something like the “dark mode” switcher plugin, I’ve come up with the below (fully functional) code

$(document).ready(function ()
{
	// This variable gets the theme ID
	var whichTheme = localStorage.getItem("theme");
	// This variable gets the active theme's actual URL
	var activeTheme = localStorage.getItem("activeTheme");
	// This variable appends the dropdown list to the existing panel
	var panel = $('<li id="switcher" class="notifications dropdown xs navbar-form"> \
<label for="user-control-list-check" class="dropdown-toggle" data-toggle="dropdown" id="user_dropdown" title="" role="button" data-original-title="Theme" aria-expanded="false"> \
<a title="Theme Switcher" href="#"><i class="fa fa-fw fa-lightbulb-o"></i><span class="visible-xs-inline">Theme Switcher</span></a> \
	</label> \
    <ul id="theme" class="dropdown-menu"> \
    <li><a id="default" href="#" rel="https://domain.com/assets/client.css?v=e02phpkima0">Default</a></li> \
    <li><a id="Dark Neon Aqua" href="#" rel="https://domain.com/assets/customcss/dark_neon_aqua.css?version=1">Dark Neon Aqua</a></li> \
    <li><a id="Dark Neon Blue" href="#" rel="https://domain.com/assets/customcss/dark_neon_blue.css?version=1">Dark Neon Blue</a></li> \
    <li><a id="Dark Neon Green" href="#" rel="https://domain.com/assets/customcss/dark_neon_green.css?version=1">Dark Neon Green</a></li> \
    <li><a id="Dark Neon Solary" href="#" rel="https://domain.com/assets/customcss/dark_neon_solary.css?version=1">Dark Neon Solary</a></li> \
    <li><a id="Dark Neon White" href="#" rel="https://domain.com/assets/customcss/dark_neon_white.css?version=1"">Dark Neon White</a></li> \
    <li><a id="Eva 00" href="#" rel="https://domain.com/assets/customcss/eva_00.css?version=1">Eva.00</a></li> \

    <li><a id="Eva 02" href="#" rel="https://domain.com/assets/customcss/eva_02.css?version=1">Eva.02</a></li> \
  </ul> \
</div> ');

	// See if there is an active theme selected in localStorage. If none selected, use the default. If there is a theme in localStorage, use that and apply it
	if (whichTheme)
	{
		$("head").append("<link href='" + activeTheme + whichTheme + " type=\'text/css\' rel=\'stylesheet\' />");
	}
	else
	{
		// No need to include anything here as there's no CSS to add.
	}

	$('ul#logged-in-menu').prepend(panel);
	$('ul#logged-out-menu').prepend(panel);

	if (utils.findBootstrapEnvironment() === 'xs')
	{
		$('#menu').prepend(panel);
	}

	$(document).ready(function ()
	{
		// Listen to the NAV dropdown for any changes
		$("#theme li a").click(function ()
		{
			// If we detect a change, append the selected CSS file into the DOM 
			$("head").append("<link href='" + $(this).attr("rel") + $(this).attr("id") + " type=\'text/css\' rel=\'stylesheet\' />");
			// This variable stores the selected theme ID
			var selected = $(this).attr("id");
			// This variable stores the selected theme link 
			var theTheme = $(this).attr("rel");
			// This variable updates the selected theme ID
			// See if "default" has been selected. If it has, then...
			if (selected === 'default')
			{
				localStorage.setItem("theme", "");
				// This variable will strip the current appended theme ID
				localStorage.setItem("activeTheme", "");
				// This variable will strip the current appended theme URL (HREF)
				// Finally, we have to reload the page to effect the changes
				location.reload();
			}
			// If any other theme is selected, carry on as normal, and update localStorage
			else
			{
				localStorage.setItem("theme", selected);
				// This variable updates the actual href of the CSS file
				localStorage.setItem("activeTheme", theTheme);
			}
			// We use return false to prevent the browser from reloading or following any HREF links
			return false;
		});
	});
});

This has been applied against the test site, and is proven to work 100%. It’s based on jQuery and is far more efficient than the previous versions above. Test it out, and let me know ref thoughts etc…

First, I wanted to thank you for your great job

I have a lot of questions !

I don’t see a modification on client.css our my custom css file?
Just JS for all that ? No modified other file?
How do you fix the yesterday problem for CSS on chat? (How do you include default client.css with my custom CSS files?)
My custom CSS on ACP/custom CSS is just for default Theme (yes If I understood correctly) ?
Can I disable all my customcss code on body.lightout variables on ACP/Custom CSS, (used for night mode) ?
Can I add other theme? --> Just add following if I’m not mistaken?

And I have other cosmetic request :

How can I fix this little problem with the spacing between the search icon–the theme switcher icon–notification icon?
I have not mouse over color on theme switcher icon like other icons on navbar?

It’s the same for all themes:

When I select a theme, I have this, how to fix these :

+On Mobile, can we delete these 2 lines

On mobile again, my wallpaper doesn’t apply (It was the case before, like default theme on ACP/custom CSS, the css code is the same)
I have this on console, normal ?

For resume, If I want to do all reproduce all that on production, If I understood correctly :

Disable Night Mode. Rebuild NodeBB
Copy my CSS file on prod server at the same repertories (or other if I change the JS code)
Copy Paste your Custom JS Code on ACP/Custom JS
Recover with Broswer Console the code ?v=XXXXX used by noidebb instance
Modify URL of Stylesheets with my css custom files path and ?v=XXXXX on your JS Code
Rebuild NodeBB

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

That’s correct. There is no need to modify any of the custom CSS files

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

Just JS for all that ? No modified other file?

Yes - jQuery in fact. You no longer require the widget HTML either as it’s now all wrapped in a custom function.

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

How do you fix the yesterday problem for CSS on chat? (How do you include default client.css with my custom CSS files?)

The default CSS is loaded by NodeBB, so will always be there. The custom function I wrote uses .append to simply add the custom CSS to what is already there

My custom CSS on ACP/custom CSS is just for default Theme (yes If I understood correctly) ?

No. That’s a global setting. No matter what is loaded by the custom function, these additional styles will always be added inline.

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

Can I disable all my customcss code on body.lightout variables on ACP/Custom CSS , (used for night mode) ?

Yes

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

Can I add other theme? --> Just add following if I’m not mistaken?

Yes, you can. You just need to copy the same format with different theme names, ID’s, and of course, the rel link.

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

How can I fix this little problem with the spacing between the search icon–the theme switcher icon–notification icon?

Looks like it’s already fixed ?

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

You can instate that using class .dropdown-toggle:hover

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

When I select a theme, I have this, how to fix these :

This also seems to be fixed ?

@downpw said in [NODEBB] CSS Style Sheets SelectBox:

On Mobile, can we delete these 2 lines

That is controlled by CSS class .navbar-form using box-shadow: inset 0 1px 0 rgba(255,255,255,.1),0 1px 0 rgba(255,255,255,.1); so you’d need to either modify that, or remove it using box-shadow: none;

I noticed this also, but now note that the wallpaper seems to be the same even on desktop despite the color being switched. Is this intended, as this was not the case yesterday ?

No change, It’s because I have Custom Header code on ACP (Your Reading Meter Bar) and he bug the css code of others theme except default theme.

Any code adding on ACP/Custom Header like a div for example crashes CSS themes :

If i disable code in ACP/Custom Header. The CSS custom themes is OK except wallpaper on Mobile

I have test with that on ACP = doesn’t work :

.dropdown-toggle:hover {
    background: #3C3C3C;

But Ok with this code but the background doesn’t occupy the entire height of the navbar like other navbar icons :

.notifications.dropdown.xs .dropdown-toggle:hover {
    background: #3C3C3C;
}

Here, this is OK. Iwould like this result:

phenomlab

@downpw Ok. Let me have a look

phenomlab

@DownPW I’ve set this custom CSS in your ACP

// PLEASE DO NOT DELETE THIS

.header #theme_dropdown {
    padding: 9px 15px;
}
.header #theme_dropdown {
    padding: 9px 15px;
        padding-top: 9px;
        padding-bottom: 9px;
    margin-top: -6px;
    padding-top: 14px;
    padding-bottom: 13px;
}

This is the basis which should make it work, but you’ll need to “fiddle” with it to get it how you need.

I also changed the jQuery code slightly, as I realized there was a conflict with another ID, which I’ve fixed.

EDIT: It’s this line

<label for="user-control-list-check" class="dropdown-toggle" data-toggle="dropdown" id="***theme***_dropdown" title="" role="button" data-original-title="Theme" aria-expanded="false"> \

DownPW

OK Thanks.
You have change id="user_dropdown with id=“theme_dropdown”

Can you will see for others problem after?

phenomlab

@downpw I’m running low on free time now sadly, but more then happy to get this resolved for you tomorrow or later in the week of that works for you.

The issue here is that I’ve reused some of the existing code from NodeBB and that may be causing some issues. Don’t worry. We’ll get there

OK Thanks sir
I really hope ! You are a super hero !

I also hope that when done this will work on future nodeBB updates/upgrade.
PM me when you have the time for that I turn on the VM

phenomlab

@downpw no issues. It’ll work across upgrades as it’s a standard function and doesn’t rely on any NodeBB components. If you can just ensure that the VM is available around the same time each day, that would also help.

Ok no problem Sir

@downpw Right. I think I have this working the way you’d like

This uses the below CSS I have placed into your ACP. It should not be deleted

// PLEASE DO NOT DELETE THIS

.header #theme_dropdown {
    padding: 9px 15px;
    padding-top: 9px;
    padding-bottom: 9px;
    margin-top: -4px;
    padding-top: 14px;
    padding-bottom: 16px;
}
#switcher{
    position: absolute;
    right: 33%;
}

The :hover class is always going to look like the below

The reason for this is because you have it hard coded in the ACP CSS as below

/*VIOLENCE: Couleur du background au survol souris */
.navbar-default .navbar-nav>li>label:hover {
    background: #555555;
}

You should remove this, and set it based on the color you want in each external CSS file. This way, it will display correctly.

The slight caveat with this is that it has to use absolute positioning meaning that if you resize the browser, the theme switcher icon will use a percentage to work out where it needs to be, and won’t be governed by the <ul><li> it sits inside. This is the only way to get the effect you are looking for.

Hmmm, it’s problematic. It’s not very aesthetic.
I am amazed because it works very well on your site or with night mode.

I see red background too on fa -faw ???
