Twenty Twelve – textblocks

Another thought – where could I alter this display – if possible – in the stylesheet – which template would that be in?

Try this in your Custom CSS option, or in child theme stylesheet.

.single-post .hentry,
.page .hentry {
	max-width: 600px;
	margin-left:auto; margin-right: auto;
}

Hi Paul thanks for that – but I found a way around. I installed a WordPress plugin called Easy Columns and here is the link on how to use it

It’s fine for my needs for now – however I may be back here sometime to pick up that code. Cheers
