Create a circular button in BS3 - css

Question

I want to create a rounded button in BS3 (a perfect circle), with a single fontawesome(4.0) icon in the center.
So far, I have the following code:
HTML:
<i class="fa fa-user"></i>
What would the CSS markup be to make this button a perfect circle?

Answer 1

you can do something like adding a class to add border radius
HTML:
<i class="fa fa-user"></i>
CSS:
.btn-circle {
width: 30px;
height: 30px;
text-align: center;
padding: 6px 0;
font-size: 12px;
line-height: 1.42;
border-radius: 15px;
}
in case you wanted to change dimension you need to change the font size or padding accordingly

Answer 2

(Not cross-browser tested), but this is my answer:
.btn-circle {
width: 40px;
height: 40px;
line-height: 40px; /* adjust line height to align vertically*/
padding:0;
border-radius: 50%;
}
vertical center via the line-height property
padding becomes useless and must be reset
border-radius independant of the button size

Boostrap 3 has a component for exactly this. It's:
<span class="badge">100</span>

Answer 4

This is the best reference using font-awesome.

CSS:
.btn-circle { width: 30px; height: 30px; text-align: center;padding: 6px 0;font-size: 12px;line-height: 1.428571429;border-radius: 15px;}.btn-circle.btn-lg {width: 50px;height: 50px;padding: 10px 16px;font-size: 18px;line-height:1.33;border-radius: 25px;}

Answer 5

With Font Awesome ICONS, I used the following code to produce a round button/image with the color of your choice.
<code>
<span class="fa fa-circle fa-lg" style="color:#ff0000;"></span>
</code>

I had the same problem and came up with a very simple solution working for all (xs, sm, normal and lg) buttons more or less:
.btn-circle {
border-radius: 50%;
padding: 0.1em;
width:1.8em;
}
The difference between the btn-xs and -sm are only their padding. And this is not covered with this snippet. This snippet calculates the sizes based on the font-size only.

If you have downloaded these files locally then you can change following classes in bootstrap-social.css, just added border-radius: 50%;
.btn-social-icon.btn-lg{height:45px;width:45px;
padding-left:0;padding-right:0; border-radius: 50%; }
And here is teh HTML
<a class="btn btn-social-icon btn-lg btn-twitter" >
<i class="fa fa-twitter"></i>
</a>
<a class=" btn btn-social-icon btn-lg btn-facebook">
<i class="fa fa-facebook sbg-facebook"></i>
</a>
<a class="btn btn-social-icon btn-lg btn-google-plus">
<i class="fa fa-google-plus"></i>
</a>
It works smooth for me.

Use font-awesome stacked icons (alternative to bootstrap badges). Here are more examples: http://fontawesome.io/examples/
.no-border {
border: none;
background-color: white;
outline: none;
cursor: pointer;
}
.color-no-focus {
color: grey;
}
.hover:hover {
color: blue;
}
.white {
color: white;
}
<button type="button" (click)="doSomething()"
class="hover color-no-focus no-border fa-stack fa-lg">
<i class="color-focus fa fa-circle fa-stack-2x"></i>
<span class="white fa-stack-1x">1</span>
</button>
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>

To add a rounded border in any button the best way is to add the border-radius property. I belive this class is better because you can add-it at any button size. If you set the height and widht you will need to create a "rouding" class to each button size.
.btn-circle {
border-radius: 50%;
}
<button class='btn-circle'>Click Me!</button>
<button class='btn-circle'>?</button>
