just like this forum, how it is possible to upload a background picture on my site? Any answers are welcomed
The first thing I would do is use the browser inspector. That will allow you to see the HTML and the CSS they are employing.
Without getting too much into the weeds here which is mostly generalised CSS, a simple solution is to do something like:
body {
background-image: url($myimageurl);
background-repeat: no-repeat;
background-position: center;
}
They seem to be doing something similar.
Make sure you’ve read through all the relevant articles in here: Topics tagged themes
Thanks that is very helpful, and it did works but there is one issue, that every block is like transparent glass
the EVE has not such issue, do you have any suggestion for that.
Yes, look around the CSS themes in Topics tagged theme-full for ones with background images and take a look at how they add opaqueness. Always good to draw on prior art. Eg Geometric, a dark theme for Discourse
