Center background for inline block - css

Question

Given HTML:
<div id="title">Text</div>
<div class="circlecontainer">

</div>
And CSS:
div {
display: inline-block;
}
.circlecontainer {
background: #E0E;
text-align:center;
line-height:200px;
width:200px;
height:200px;
}
.circle {
width:100px;
height:100px;
border-radius: 50px;
font-size:20px;
color:#fff;
background:#000
}
.circle:hover {
width:200px;
height:200px;
border-radius: 100px;
}

I would like the black circle to be vertically centered when not hovered over.
But when I set vertical-align:middle, the text looks screwed up:

Why does this happen?

Answer 1

It's because the line-height is still 200px. Try this:
div {
display: inline-block;
}
.circlecontainer {
background: #E0E;
text-align:center;
line-height:200px;
width:200px;
height:200px;
}
.circle {
line-height: 100px;
position: relative;
vertical-align: middle;
width:100px;
height:100px;
border-radius: 50px;
font-size:20px;
color:#fff;
background:#000
}
.circle:hover {
width:200px;
line-height: 200px;
height:200px;
border-radius: 100px;
}

Answer 2

If you remove the border-radius the box is not centered, so the circle is not centered too
You need to work with the margin-top. I've edited your fiddle

Answer 3

Simply add a span tag inside the circle div element with style "vertical-align: middle;" and remove the "vertical-align: middle;" of the circle class.
<div class="circle">
<span style=" vertical-align: middle;">Hello</span>
</div>
The problem is because of the height of the circle class change also affect the text element. With the span, it does not.
