Aligning characters according to Unicode standards

Question

Aligning characters according to Unicode standards

I'm looking to showcase a Unicode character at the center of a button. Below is the code snippet:

<div class="col-xs-1">
    <button class="btn btn-tool">
      <span></span>
    </button>
  </div>

span:before {
  font-family: "Arial Unicode MS";
  content: "\25cf";
  font-size: 3em;
  vertical-align: middle;
}

Following the suggestions at this link, I attempted to adjust the character's size using

font-size

and

vertical-align.

However, when viewing the JSFiddle, the alignment did not turn out as expected (character centered both horizontally and vertically). Any assistance would be appreciated.

Answer №1

There are various ways to center elements horizontally and vertically. Below is my preferred method:

.btn.btn-tool {
  position: relative;
  height: 200px; /* added height and width for demonstration only */
  width: 80px;
}
span:before {
  font-family: "Arial Unicode MS";
  content: "\25cf";
  font-size: 3em;
  display: block;
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  text-align: center;
  width: 100%;
}

<button class="btn btn-tool">
  <span></span>
</button>

If you want to adjust the alignment, consider modifying the line-height instead of using vertical-align. See the example here: https://jsfiddle.net/39a4grvh/

.btn-tool {
  width: 30px;
  height: 30px;
  padding: 0;
  background-color: #4f4f4f;
  color: #a19d9d;
  line-height: 0.5;
}

span:before {
  font-family: "Arial Unicode MS";
  content: "\25cf";
  font-size: 3em;
}
