Hi Mary - that's what I want to achieve. I think there is something missing from my understanding though.
I cut and paste the CSS from your example
#page-front-right .block_html {
height: auto;
width: auto;
min-height: 250px;
min-width: 400px;
border: 0 none;
}
into the 'Configure HTML Block' 'Content' editor in 'Edit HTML source' mode.
the result just showed the CSS as part of the text in the editor and in the resultant HTML block.
I tried cutting and pasting it into the Frontage.php file using FTP and that just resulted in a blank screen at the user front page (I'm running a pretner person on my iPad in parallel to any editing I'm doing on the main computer screen) - I restored using a backup copy of the Frontage.php file and its working as it was before.
So I think my question is, where do I add the CSS to style it
Added later:
I just found an article that prompted me to enable 'Additional CSS Classes' for HTML Blocks.
(from Settings>Site administration>Plugins>Blocks>HTML, toggle the ability to allow additional CSS classes to be set in individual block instances. If it is enabled, a field appears at the bottom of HTML block instance's configuration forms
I've done this and copied the additional CSS in there. still no joy.
