Can't Quite Place Background Image

Looking at
.imageA
code - I am trying to place a background image into this element. I thought from watching a YouTube video on the subject that
<img src="https:unsplash.it/400/200">
would return a random image from Unsplash with dimensions of
W400 H200. I think there might be an additional step that I am missing here but I can’t figure out what.

you can’t put an html tag in the css

if you want to give a background image to the .imageA class you need to use the appropriate property, for example this:

also I think the url you have is wrong, it can’t start with https: it needs to be https://

ah yes - html belongs in the body not the CSS - how embarrasing🙃
thanks for setting me straight - I’m spending too much time on this at one sitting - that’s the problem🙂
