Answer 1

.bluebox {
width: 400px;
background-color: blue;
height: 200px;
position: relative; /* allow absolute positioning within */
}
.bluebox h2 {
font-family: Arial;
font-size: 10pt;
text-align: center;
position: absolute; /* positioning */
top: 50%; /* 50% from the top (half way) */
margin-top: -5pt; /* bring it back up half the height of your text size */
width: 100%; /* to allow for the text align */
}
Example at http://jsfiddle.net/zTPgh/1/ - Change the height of the container and run or update to see it in action.

You can play with display: table-cell;.
Your new CSS:
.bluebox {
width: 400px;
background-color: blue;
height: 150px;
display: table-cell;
vertical-align: middle;
}
.bluebox h2 {
font-family: Arial;
font-size: 10pt;
text-align: center;
}

See my tutorial here which will vertically align and center text and images. DON'T rely on line-heights as you'll have huge gaps between lines of text. http://www.andy-howard.com/verticalAndHorizontalAlignment/index.html

For aligning an element vertically center, I have used css3 calc() function. It's perfectly working in all the latest browsers including ie11 and edge.

.calcTest { width: 250px; height: 250px; border:1px solid #e0e0e0; text-align: center; }
.calcTest .calcTestInner { width: 50px; height: 50px; background: #e0e0e0;
margin: 0 auto; margin-top: calc(50% - 25px); vertical-align: top; }
<div class="calcTest">
<div class="calcTestInner">
