fix less / css

[brianteeman]

recompile less using our generatecss.php script

Most changes seem to be codestyle - i guess someone used a different less compiler

BUT check the changes to input-prepend

[Bakual]

The input-prepend stuff is related to this PR that was merged lately: #12442

[Bakual]

Btw: https://github.com/joomla/joomla-cms/blob/3.7.x/media/jui/less/bootstrap-extended.less#L376-L383 doesn't look right (and is also related to the mentioned PR).

@ciar4n can you take a look here?

I have tested this item ✅ successfully on 3e6bd2c

@brianteeman Apologies as this was most likely my doing. Noted for future PRs! :)

@Bakual I emptied these selectors for #12442 . As empty selectors are ignored by LESS, I didn't bother removing them.

You should have, as empty selectors are useless 😄

[ciar4n]

@Bakual True :) They are not outputted to the CSS so no ill effect for the time been. I'll remove them at the next given chance.

@zero-24 @Bakual can you guys test this so we can get it merged and then other PRs wont be effected by this error

Tested with Protostar, Isis and my own template and couldn't see any notable difference.
