It's become obvious that these random floating points everywhere
are unwieldy. Now they're all in one place with some fairly logical
variable names which will help out in design->implementation phase.
Font size of the whole app would ideally be controlled by a single
value. This value is currently hard coded using the :root CSS selector.
It is the intention to make this value configurable within riot. In the
interim all font-sizes have been converted to rem by the simple process
of regex. Replacing px values with their equivalent rem values assuming
a font size of 15px and then rounded to three decimal places, which was
the base at the time of this transformation.
I'm expecting another commit cleaning up rem values but I thought it
best to leave that to review.
This commit doesn't address any scaling issues. I thought it better to
land this unwieldy, mechanical, invisible change before the others
otherwise the pr would be impossible to review thoroughly.
Fixes https://github.com/vector-im/riot-web/issues/10554
Issues fixed:
* Fields were not ~30px from the avatar (too much right margin)
* Tooltips overflowed the dialog on some resolutions
* SetIdServer didn't have an error state for making the field red
* Spacing between sections in Discovery was wrong (fixed by just removing the problematic n+2 selector - it didn't help anything)
This makes a few small tweaks to Settings padding and margin, but more is still
needed. I am told that https://github.com/vector-im/riot-web/issues/10554 will
soon take a holistic view on the problem, so this is a more conservation
temporary change.
Also bring in the compact timeline option.
Without minor CSS changes, the old user settings are completely unusable with this change. As such, minimal effort has been put in to have it be useful. Similarly, the changes drop the use of radio groups and the old theme selector was the only one that used it. See the comments for more details on how/why this was mitigated the way it was.
