Question

How can I vertically centre an unknown quantity of text (may span multiple lines) in a div of known height. I know it can be done using the line-height property however this only works when there is only one line of text.

Answer 1

I have actually found the answer to what I need myself.

.info, .success, .warning, .error, .validation {  
border: 1px solid;
margin: 10px 0px;
padding:15px 10px 15px 50px;
}

.info {
color: #00529B;
background-color: #BDE5F8;
}

.success {
color: #4F8A10;
background-color: #DFF2BF;
}

.warning {
color: #9F6000;
background-color: #FEEFB3;
}

.error {
color: #D8000C;
background-color: #FFBABA;
}

The ‘trick’ so-to-speak is to not set a height for the div and just set padding/margins to do the centring.
