OK well I have found the issue…and, well, it’s my mistake but I’m not sure if it could also be considered a bug.
Initially while styling my navbar header, I took some CSS (from a post here on Apex) so that I could style a gradient colour. This was added to CSS in the header builder. However, I then decided that I didn’t like it so I commented it out. Like this.
/*
.hm5 .x-dropdown,
.headcol {
background: #c32755; /* Old browsers */
background: -moz-linear-gradient(left, #c32755 0%, #414c90 100%); /* FF3.6-15 */
background: -webkit-linear-gradient(left, #c32755 0%,#414c90 100%); /* Chrome10-25,Safari5.1-6 */
background: linear-gradient(to right, #c32755 0%,#414c90 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#c32755', endColorstr='#414c90',GradientType=1 ); /* IE6-9 */
}
*/
Note that, although I commented it out using /* … / syntax, there are also similar comments on the ends of the lines. Consequently, the code wasn’t commented out like I might have expected leaving the result like this: -
background: -moz-linear-gradient(left, #c32755 0%, #414c90 100%); /
FF3.6-15 /
background: -webkit-linear-gradient(left, #c32755 0%,#414c90 100%); / Chrome10-25,Safari5.1-6 /
background: linear-gradient(to right, #c32755 0%,#414c90 100%); / W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ /
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr=’#c32755’, endColorstr=’#414c90’,GradientType=1 ); / IE6-9 */
}
*/
So this is CSS in the header, with no CSS selector. Counter-intuitively, this results in no footer styling occurring at all.
If I remove this block, the footer is back to normal.
Thanks

p.s. Sorry, I can’t figure out how to post code snippets properly in Apex.
