contrast fix for main cards

[Eccenux]

There is a very low contrast on the main page on the green card (below 2). The other cards is about 5 and 8 so acceptable. A simple fix is to change color of the text to black as in the patch.

Another option is to use darker green. But would need to be at least #809D2A to to be viable for large text and #667D21 for small text.

Oh. You can easily check contrast in Firefox dev tools (click on color: prop) or on WebAIM website:

Thanks for looking at this. It's a very valid point. Not sure which is the right option. Will try and take a look shortly if no-one else steps in first.

Unfortunately I didn't take any notice of it until now where I go through my github stuff. Is this still relevant? Is this still the repo of the website?

@Chris2011 no this repos is "deprecated" for the site UI but the constrat concern are still valid.

https://github.com/apache/netbeans-antora-ui is the home of the related ui for the site

@ebarboni thx, will have a look there.
