Fixed background to nodebb forum
Solved
Configure
-
I’ve been asked to do this:
On the forum, mobile friendly and on PC you’ll get a fire coloured gradient for the background with everything within a frame on top of that background so the frame can be scrolled but the background doesn’t change.
Centred experience such as tumblr or twitter in the sense that it’s the info that gets scrolled but not the whole pageThe forum is nodebb hosted, so although I can add custom CSS or Javascript, where can I upload the image to use?
Also what CSS to write please?@Panda this is untested as I’m not in front of a PC currently, but should work
body { background-image: url("/path/to/your/image.jpg"); min-height: 100%; background-repeat: no-repeat; background-attachment: fixed; background-position: center; background-size: cover; } The image can be hosted anywhere outside of the NodeBB ecosystem provided it is reachable from any machine with an Internet connection. It doesn’t necessarily need to be on the site itself

@phenomlab there was error, close } without opening {
Is there missing line at start?
On that topic the brackets and some words in that code block (center , cover etc) are very feint to read on my device?

Ah I figured out needed
body {Its working but got this funny response as if background is being clicked, and slightly moves sometimes, when you scroll up and down on forum content
-
Apart from the slight move issue
The dark background was also too stong and making forum text hard to read.I asked chatGPT for fix, both its suggestions didnt work
1st suggestion change alpha value on rgb made no difference
2nd idea, filter:
This only made forum text weaker!
Its now saying I need to edit the image in a paint program, and save it with more transparency, but as Im loading from website I cant do that
Is there a CSS way to reduce alpha value on image from external url?

@Panda there is. What you are seeing here with the image moving when clicked is called Cumulative Layout Shift which occurs when the body height is set incorrectly.
Filter and Opacity are a bad idea as you are targeting the
bodyelement meaning all ancestors are affected by that change which in turn makes the text even harder to read.Tired want to use a overlay with the image, to add background color with transparency which should solve the issue.

You’ll never avoid having to use it. I’d recommend you start to learn it because you’ll come across this in all aspects of web development.

@Panda yes, but you should start with a sane value and work backwards. The lower the last number in terms of
rgbathe higher the transparency. -

@phenomlab I go to admin menu and select skins
Current one is Quartz@Panda ok, but which code runs this? Is it mine, or someone else’s work (it does make a difference.
Edit - ok, unless I login, I cannot change the skin if it’s under admin. I’m being forced to wear sunglasses currently.

@phenomlab

You really need to custom develop a skin if your want it to look right.

@phenomlab yea, this is what Im asking,
Using a skin but maybe modifying one of the color choices -
@phenomlab yea, this is what Im asking,

If the one skin, then this is simple enough, but you’d need a lot of custom css to make this work.
