Font Awesome icons have text-decoration issues inside links

Question

I have a "ugly" issue with font-awesome, when I place a icon-link (icon inside a link) in front of a text. By hovering the icon, the icon itself will not get underlined but somehow the space between the text and the icon. Somehow the text-decoration css rule from the link (underline while hover) collides with the one coming from the icon in this strangely appearing space.

How can I get rid of this underline in the space and have no decoration at all in the end? (when possible without adding a class to the link element nor using JS)

Here is a code snippet that may help you.

Answer 1

Apparently your <a> tag and your <i> tag will not render a space if you write them in a single line. Avoiding line break between these two elements fixes your issue.

Code Snippet:

a {
  text-decoration: none;
}
a:hover {
  text-decoration: underline;
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css" rel="stylesheet" />
<h1>
  <a href="#"><i class="fa fa-wrench"></i></a>
  Text of Title
</h1>

EDIT:

Usually it is better if you do not change the default display value of an element, but here you can use display: inline-block; in your <a> tag to remove that space.

a {
  text-decoration: none;
}
a:hover {
  text-decoration: underline;
}
h1 > a {
  display: inline-block;
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css" rel="stylesheet" />
<h1>
  <a href="#">
    <i class="fa fa-wrench"></i>
  </a>
  Text of Title
</h1>

Not necessarily question-related but I stopped using icon fonts a while back and adopted SVG icons, which, in my opinion, are way better.

Here's a good article on making the switch, and here's another on how to use them.

DEMO:

a {
  text-decoration: none;
}
a:hover {
  text-decoration: underline;
}
h1 > a {
  display: inline-block;
  color: purple;
}
.icon {
  display: inline-block;
  width: 1em;
  height: 1em;
  stroke-width: 0;
  stroke: currentColor;
  fill: currentColor;
}
.icon-wrench {
  width: 0.939453125em;
}

<h1>
  <a href="#">
   <svg class="icon icon-wrench">
   <use xlink:href="#icon-wrench"></use>
   </svg>
  </a>
  Text of Title
</h1>
<svg style="display:none;">
  <symbol id="icon-wrench" viewBox="0 0 30 32">
    <title>wrench</title>
