html - Ensuring body height does not exceed browser height

Question

So essentially at present, I am trying to make it so the body's height never exceeds the height of the browser (E.G. there is no need for a scroll bar) as I only require my content area (which is set to I believe the div class content) to be the scrollable section.

Now I can view it on one screen size and get it looking just right by setting that content area to have I believe 70vh. But then on another screen size that same 70vh will either be smaller or larger (and thus exceed the browser's height). And I've tried setting like 100vh to the body and html and it just does nothing.

Desired result on all screens:

Current result on some screens:

index.html is located here: https://github.com/ashworthian/stprecious/blob/master/index.html

css is located here: https://github.com/ashworthian/stprecious/blob/master/css/style.css

And yes I know I need to clean my css up but just trying to get this height thing fixed first.

You'd probably need to adjust this to your code; but the basic idea is the following:

By using Flexbox; you can define a flex-container which will encapsulate the content of the page; you set this container to have a flex-direction: column, so it positions the elments inside vertically.

After that, you have to tell the section that has the scrollable content to have a property of flex: 1 1 auto; which is short-hand for flex-grow, flex-shrink, flex-basis. This will make it use all the available space that remains on the page without actually increasing the size of it.

You can read more about flexbox here: Complete Guide to Flexbox, its really worth it and will help a lot in building these kind of layouts easily without much CSS
