Change default block title colors in Footer first to fourth regions to improve contrast

Thanks for this @paulihuhtiniemi

Isn't that still over-ridden by:

#footer .block > h2 {
    clip: rect(1px, 1px, 1px, 1px);
    height: 1px;
    overflow: hidden;
    position: absolute !important;
}

I don't see the headings at all. Also, the color contrast isn't sufficient. A good tool to test is http://webaim.org/resources/contrastchecker/

Also - http://contrast-finder.tanaguru.com

Needs work per #3 I think.

This issue is currently blocked by the h2's being hidden in the footer #2148319: h2 on footer blocks must be hidden by default but must show when its enable.
The block titles in the footer need to be brought back then their accessibility can be worked on.

Also setting this issue to be a bug and a normal priority as the heading colour's do not pass contrast tests.

We should work on #2148319: h2 on footer blocks must be hidden by default but must show when its enable I believe that issue should be fixed and then we can come back to this :)

This issue is just for the titles in the footer first to fourth regions.
Un-postponing this issue for a new patch.
The patch in #1 is incorrect but the work suggested in the comment is what we need to do?! Let's create a new patch changing the titles to be the same colour as the content in footer first - fourth regions.

updated footer region one to four title color to be #ffffff, to increase contrast and differ from link color

I think this should be covered in https://www.drupal.org/node/2148319#comment-9719693

we can tackle both issue separately.

@Chloe Chen Thanks for working on this!

   There are some trailing spaces here. Can you check your editor configuration to remove white spaces at the end of each line?

   Drupal CSS coding standards suggest using shorthand colors when possible, eg. use '#fff' instead of '#ffffff'.

This one will get fixed in https://www.drupal.org/node/2148319. All the patches are resolving block header visibility issue in that issue.

Ok, so #2148319: h2 on footer blocks must be hidden by default but must show when its enable is in now. Can wee verify that this problem is resolved before we mar this as a duplicate?

@mgifford The patch in the related issue was about displaying the title in the region 'Footer fifth', while this issue is about the contrast of the titles in regions 'Footer first' to 'Footer fourth'. So while related, they are actually separate issues.

Making changes to @Chloe's patch as suggested in #10.

This issue has been resolved in #2148319: h2 on footer blocks must be hidden by default but must show when its enable. Now all block title of footer-top and footer-bottom has same color as content.

Changing status to Fixed.

This issue needs to stay as Closed (duplicate) as it's work was never committed to core.
