How to align icon and text [duplicate] - css

Question

<div class="col-md-4">
<span class="fa-stack fa-2x">
<i class="fa fa-circle fa-stack-2x blue"></i>
<i class="fa fa-wifi fa-stack-1x white"></i>
</span>
<h4 class="blue">Free wifi</h4>
</div>
How can I display h4 element on the right of the icon and vertically aligned? Should I float left the span?

Answer 1

One of the ways would be to use inline-block display and middle align it - see demo below:
.wrapper > * {
display: inline-block;
vertical-align: middle;
}
.blue {
color: blue;
}
.white {
color: white;
}

<div class="col-md-4 wrapper">
<span class="fa-stack fa-2x">
<i class="fa fa-circle fa-stack-2x blue"></i>
<i class="fa fa-wifi fa-stack-1x white"></i>
</span>
<h4 class="blue">Free wifi</h4>
</div>

Answer 2

Use CSS Flexbox. Make a parent <div> that wraps icon and text into it (in my case its icon-holder) and make it a flexbox container using display: flex.
Have a look at the snippet below:
.icon-holder {
display: flex; /* Flex Container */
align-items: center; /* Vertically Align Content */
}
.blue {
color: #33b5e5;
}
span {
color: #fff;
}
h4 {
padding-left: 5px;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>
<div class="col-md-4">
<div class="icon-holder">
<span class="fa-stack fa-2x">
<i class="fa fa-circle fa-stack-2x blue"></i>
<i class="fa fa-wifi fa-stack-1x white"></i>
</span>
<h4 class="blue">Free wifi</h4>
</div>
</div>
Hope this helps!

You can use display: flex and can do something like below :
.col-md-4 {
display: flex;
align-items: center;
}
.blue {
color: blue
}
.white {
color: white;
}
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
<div class="col-md-4 wrapper">
<span class="fa-stack fa-2x">
<i class="fa fa-circle fa-stack-2x blue"></i>
<i class="fa fa-wifi fa-stack-1x white"></i>
</span>
<h4 class="blue">Free wifi</h4>
</div>
