Guys, Do I have to set width and height properties to each element on my html so it can take up space in the webpage ?
In my .css file, I tried to change the background-color of the "body" element and nothing happened. I tried to inspect the body element using Google Chrome and I found that the body element isn't taking any space on the page, so when I sat the width value of the body element.. the background color changed.
I noticed this issue with most major parent elements such as: html, body, section, div..
Thanks for your support

Hi Ahmed, I think a good answer to your question is "yes ... and no".
No you don't have to set width and height to EVERY single element, that would make your code rather bloated and it's unpractical. But they* (body, div and etc) do need content inside of them to show on the screen, otherwise they are just empty and have no reason to show up. They're there, but unless you put some text or an image (a placeholder) elements are basically collapsed.
At the same time you can set width and height to elements if you want to force them to show at such width and height... I usually do that if I want to see how much space a div is going to take on screen! That way, usually they don't need content inside because you're telling them to be 'x' width and 'x' height.
So it really depends on what you're trying to achieve :) Do you want your element to be a certain size: set the measurements on CSS; Do you want your elements to take up the space that your content does (you should be setting some margins and paddings anyways): then place your content on your HTML to see it on the page.
Hope this sheds some light.
Many html elements will not take any space without any content in them. That is unless you specify height and width in css. Have you tried using mock content as a placeholder while building your site?

Yes I tired to put a placeholder contents, but it was a <nav> contents.. seemingly, the body element doesn't take the <nav> element as a placeholder for its designated space. So I put other elements like divs and paragraphs and the it worked.
Thanks for your support :)
