Question

CodePen

I want to align the both vertically and horizontally, the height and width of the container will be fixed regarding other extenal factors.

How do i do that?

I've tried using flex

display: flex;
justify-content: center;
flex-direction: column;

but it gets rid of my horizontal alignment

Answer 1

Actually, there are multiple ways to achieve vertical alignment, here is one:

 div { width: 300px; height: 150px; background-color: #ddd; text-align: center; font-size: 0; } div::before { content: ""; display: inline-block; height: 100%; vertical-align: middle; } a { width: 100px; height:50px; background-color: #ff0000; display: inline-block; vertical-align: middle; font-size: 16px } 

 <div> <a href="#">Some Text</a> </div>

Found the solution!

On the div parent:

position:relative;

On the a child:

position: absolute;
top: 50%;
left: 50%;
margin-left: -half_its_width;
margin-top: -half_his_height;
