如何将图标对准方形框的中心？

Question

I'm trying to align my icon inside a square div to have both properties: CENTER + MIDDLE

This is what I hope to get :

I have tried this on my CSS :

/* Slick Settings */

  .slick-next {
    right: 0px;
    border: 1px solid black;
    width:35px;
    height:35px;
    padding: 5px;
    display:table;
    text-align: center;
  }

  .slick-prev {
    left: 360px;
    border: 1px solid black;
    width:35px;
    height:35px;
    padding: 5px;
    display:table;
    text-align: center;
  }

  .slick-next:before {
    font-family: FontAwesome;
    content:"\f105";
    color:black;
    display: table-cell;
    vertical-align: middle;
    left: 50%;
  }

  .slick-prev:before {
    font-family: FontAwesome;
    content:"\f104";
    color:black;
    display: table-cell;
    vertical-align: middle;
    left: 50%;
  }

This is what I produce :

Can someone help me with this ?

Feel free to suggest me if you have any other better way of archieving this.

Thanks in advance.

Answer 1

You could also do it this way.

 .slick-next { border: 1px solid black; width: 40px; height: 40px; text-align: center; } .slick-next:after { display: inline-block; vertical-align: middle; content: ""; height: 100%; } 

 <link href="http://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet"/> <div class="slick-next"><i class="fa fa-angle-right"></i></div> 

Answer 2

left: 50%; would only work on an absolutely positioned element. So set those styles to position: absolute; or center them with the margin property like this:

margin-left: auto;
margin-right: auto;

Answer 3

Maybe you can set display to BLOCK for before pseudoelement and set line-hight of it to match DIV. That will center text vertically. Placing text-align to center and width to 100% will center text horizontally.

  .slick-prev { border: 1px solid black; width:35px; height:35px; } .slick-prev:before { font-family: FontAwesome; content:"\\f104"; color:black; display: block; text-align: center; width: 100%; line-height: 35px; } 

 <div class="slick-prev"></div> 

Answer 4

Opp...

After playing around with my CSS. This seem to do the trick.

/* Slick Settings */

.slick-next {
  right: 10px;

  border: 1px solid black;
  width:35px;
  height:35px;
  padding: 5px;
  display:table;
  text-align: center;
  margin-left: auto;
  margin-right: auto;
}

.slick-prev {
  left: 360px;

  border: 1px solid black;
  width:35px;
  height:35px;
  padding: 5px;
  display:table;
  text-align: center;
  margin-left: auto;
  margin-right: auto;

}

.slick-next:before {
  font-family: FontAwesome;
  content:"\f105";
  color:black;


}

.slick-prev:before {
  font-family: FontAwesome;
  content:"\f104";
  color:black;


}

I think I am all-set. I got it now.
