Hello,
Thank you for all this. I'm trying to experiment with the CSS as you suggest, it's a great way to learn.
I Validate the page and it's great to see only one error as I set it up, the only ting is I don't understand the error!
It reads
Line 32, Column 25: end tag for "br" omitted, but OMITTAG NO was specified
<h2>1st build</h2><br>✉
You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".
Line 32, Column 21: start tag was here
<h2>1st build</h2><br>
Thank you,
Best wishes
Graeme
