Cannot get the tagline to the center + text wrapping

Question

I'm very new to this, so it might be a very dumb question.

I can't get the text to wrap if I set the position to absolute instead of relative. The aim is to have the tagline stay in the center all the time with the text wrapping.

I'm using wordpress CSS. Here's my code:

.tagline {
max-width: none;
text-overflow: initial;
white-space: normal;
position: relative;
top: 240px;}
