[0d89044: Replace gradient images with CSS gradients.] replaced gradient
images with CSS gradients but in doing so changed some of them from
light blue to gold. Change the colours to correct ones where necessary.
Because #logobutton had a fixed width, browser window narrower than 933
pixels resulted in an unnecessary horizontal scroll bar. Fix that by
using a dynamic 100% width which results in the header image being
automatically clipped as necessary.
To avoid clipping the tree and the text though, include min-width so
that very narrow windows result in a horizontal scroll bar so the whole
name can be seen.
Furthermore, simplify the markup by removing wrapper DIV and SPAN
elements which weren’t really necessary. As a consequence of that
change, the whole top of the page is now a link to the homepage (i.e.
‘/’). Prior to this change, the link wasn’t clickable.
In this situation:
<body class="conservancy-blog">
...
<video>
it turned out that this CSS:
body.conservancy-blog video {}
Did not apply.
So, this adds a hack to force the issue.
I noticed after I updated to jessie that fonts displayed strangely in
some browsers. I still have strange fonts on our website with Chromium,
but this change seems to have helped iceweasel.
