Centering icon font in css circle, inside of parent

Question

Ok so I have 3 css circles with icon fonts centered inside of them, now I cant for the life of me get it centered inside of its parent. Also instead of lining up they are stacking on top of each other, I used float: left to fix this but it messed up my whole hover.

Take a look here, just go to portfolio section and hover over one of the members.

How it is suppose to look:

How it looks:

HTML:

<ul class="img-list">
  <li>
    <img src="img/team-member-1.jpg" alt="...">
    <span class="text-content">
        <span>
            <div class="social-icon-holder">
                <span class="ion-social-twitter social-icon"></span>
            </div>
            <div class="social-icon-holder">
                <span class="ion-social-facebook social-icon"></span>
            </div>
            <div class="social-icon-holder">
                <span class="ion-social-dribbble social-icon"></span>
            </div>
            Johnathan Adams

Answer 1

from my comment: http://jsfiddle.net/h7kJS/ full result : http://jsfiddle.net/h7kJS/2/embedded/result/ .social-icon-holder can be displayed as inline-table (inline-block+line-height works too).

Image should be in absolute under .text-content to make things easier :below: update of your CSS (where .team was removed for .img-list )

    /* =Team
-------------------------------------------------------------- */
.img-list {/* update */
    padding: 180px 0 180px 0;
}

.img-list img {/* update */
    width: 100%;
    height: 100%;
    position:absolute;/* update */
    z-index:0;/* update */
}

ul.img-list {
    list-style-type: none;
    padding: 0;
}

ul.img-list li {
    display: inline-block;
    position: relative;
    height: 350px;
    width:350px;/* update */
}

span.text-content {
    background: rgba(39,39,39,0.75);
    color: white;
    cursor: pointer;
    display: table;
    left: 0;
    top: 0;
    opacity: 0;
    width: 100%;
    height: 100%;
}

span.text-content span {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
    height:100%;
    width:100%;
}

ul.img-list li:hover span.text-content {
    opacity: 1;
    transition: opacity 500ms;
    position:relative;/* update */
}

.team span p {
    font-family: 'Montserrat', sans-serif;
    text-transform: uppercase;
    font-size: 14px;
    color: #a5a5a5;
}

.social-icon {
    font-size: 12px;
    color: #fff;
    margin: 0 auto;
    display: table-cell;
    vertical-align: middle;
}

.social-icon-holder {
    border: 2px solid #fff;
    border-radius: 50%;
    width: 30px;
    height: 30px;
    display: inline-table;/* update */
}

.social-icon-holder:hover {
    background-color: #fff;
    cursor: pointer;
}

.social-icon-holder:hover .social-icon {
    color: #272727;
    cursor: pointer;
    transition: color 0.5s ease;
}

Answer 2

Wrap a <p> tag around the team members name to make it a block element and essentially put it on a new line.

Then, in .social-icon-holder{

change

display:table;

to

display:inline-block;

or

display:inline-table;

JsFiddle

For this JsFiddle, I jut used a placeholder background image.

To get the social icons center, I did this:

.social-icon {
    font-size: 12px;
    color: #fff;
    display: block;
    text-align:center;
    width:30px;
    height:30px;
}

Answer 3

you have to remove display :table from the class .social-icon-holder and then you may add display: table-cell; property.

also to align the icons inside the circle you can add font-size and a little bit padding.

HEre I've just added for facebook icon, but you can apply it on .social-icon so apply for all icons.

.ion-social-facebook:before {
content: "\f231";
font-size: 2em; /*Added line this will increase the icon size*/
padding-left: .4em;
}

Answer 4

Try doing this:

<span>
 <div class="social">
   <div class="social-icon-holder">
      <span class="ion-social-twitter social-icon"></span>
   </div>
   <div class="social-icon-holder">
      <span class="ion-social-twitter social-icon"></span>
   </div>
   <div class="social-icon-holder">
      <span class="ion-social-twitter social-icon"></span>
   </div>
 </div>
</span>

--- stylesheet --

.social div{
  display: inline-block;
}

.social-icon{
  padding: 8px 10px;
}

Answer 5

Is it ok ? try this code

.social-icon-holder {
    border: 2px solid #FFFFFF;
    border-radius: 50%;
    height: 30px;
    width: 30px;

   display: block;
   margin: 0 auto;
}
