Question

My code is

HTML:

<div id = "container">
  <div id = "content">
      Text
  </div>
</div>

CSS:

div {
  border: 1px solid;
}

#container {
   display: block;
   width: 100%;
   height: 60px;
   margin: 0;
   padding: 0;
   font-size: 24px;
}

#content {
   display: inline-block;
   vertical-align: middle;
}

Set font-size: 0; for parent container and font-size: your_size; for children.
