Why is my manually set width set to auto?

Question

I manually set widthhow 67px. As you can see, dev tools show the following:

#tango-directive-template .tango .left-icons {
  width: 67px;
}

But, as you can see, the actual widthis just that 39.964px. It is installed on autoand calculated by the browser.

Why is this? And how should I prevent this?

spanby default have display: inline;. Browsers ignore any widths or heights set on inline elements; they behave as if they are just text.

If you want to set widthfor an element, use display: block;or display: inline-block;.
