Align Text Beside FontAwesome Icon

There is a very easy way if your fontawesome has the same font-size than your text (it is usually the good practice), include the tags in the text tags:

<p>
  <i class="fa fa-check"></i>
 Text text text
</p>

Use the .media class.

<div class="media">
    <div class="media-left">
        <i class="fa fa-home"></i>
    </div>
    <div class="media-body">
        Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.
    </div>
</div>

To have complete/independent control on the position of the font-awesome icon, try something like below.

Method 1: Using absolute positioning

1. Add position with a property value of relative to the h3 style to control overlap.

2. Use :after selector content to insert the icon

3. Add position with a property value of absolute to the h3 :after block of CSS code

4. Achieve the desired position with left, right, top or bottom property values.

Method 2: Using float(Easier).

1. Use :after selector content value to insert the icon

2. Achieve the desired position of the icon by floating the :before selector to the right or left.

/* Using absolute positoinning */

h3.absolute {
  position: relative; /* Helps us control overlap */
  padding-left: 25px; /* Creates space for the Phone Icon */
  }

 h3.absolute:before {
  content: '\f095';
  font-family: fontAwesome;
  position: absolute;
  left: 0; /* Adjust as needed */
  top: 3px; /* Adjust as needed */
  }
  
 /* Using float */

  h3.float {
  font-size: 24px;
  color: red;
  }

 h3.float:before {
  content: '\f095';
  font-family: fontAwesome;
  float: left; /* Depends on the side we want the icon */
  margin-right: 10px; /* Creates space between the icon and the text */
  font-size: 24px;
  height: 32px;
  line-height: 32px; /* Same as the font size */
  }
  
  
  /* Below code is jsut for differentiation of methods */
  strong {
  font-size: 24px;
  text-decoration: underline;
  display: block;
  width: 100%;
  }
  
  strong:last-of-type {
  color: red;
  }

<strong>Using absolute Positioning</strong>
<h3 class="absolute">Call us</h3>

<strong>Using float</strong>
<h3 class="float">Call us</h3>

Note: You can adjust the size of the icon with CSS font-size property value.

Try this :

<i class="fa fa-phone fa-2x" style="vertical-align: middle;"></i>
