CSS Question

Why Wont vh Work In Chrome, but It Works In Internet Explorer

So, I am using

vh
, and, to my knowledge, it is
1 percent
the view height of the page. It should work like percentages, but for borders and possibly other things. In Chrome, though, it wont work and leaves white space at the bottom of the Web page. Here is what I am using:

div /*It most be any element I'm just using div for an example*/
{
border:.5vh solid red;
}


I am asking this because Chrome (being the frustrating piece of work it is) doesn't convert
.1vh to .1%
like like internet explorer does and I'm left with white space at the bottom. Here is what I'm working on:

If you look closely at the bottom of the Web page (on Chrome), you can see white space at the bottom of the page. You have the really look at the bottom to see it. This doesn't happen on Internet Explorer (I'm using a pre-installed version of IE on windows ten, but I don't know what version). If you don't get the same problem, I get I'm sorry that this wasted your time, but I can show you screenshot proof if you really want it.

Things to note:

I have two other pages so there maybe be other things in my css text document that you may encounter. Ignore it.

If percentages don't work than is there another way to simulate them for borders in Chrome?

Thank you for for your time!

Answer

In Chrome, border widths are rounded down to the nearest pixel. Depending on the calculated results of your vh border widths, the sum of the heights and border widths of all your elements may be less than 100%.

You can solve this by applying box-sizing: border-box to all of your elements. This will ensure borders do not change the dimensions of your elements, so you'd only have to ensure your <div> heights add to 100%.

* {
    box-sizing: border-box;
}

However, you choose to do it, never use fixed heights if you can avoid it. Let CSS handle the dimensions naturally.
