IMHO the prior font choice was not exactly display friendly (I thought it was a bit ugly, pixelated etc) so i've switched to font-family: 'Noto Sans', 'Trebuchet MS', Helvetica, Arial, sans-serif; as well as causing the size to be 1.09375em/1.4 as default. I have noticed considerable fallout from this change, some text is much larger than it had been, some is strangely unchanged, etc. The eventual intent is for sizes to be percentages drawn from any default size in em (I think thats how I was doing things on forums.pcbsd.org) and I would strongly consider having only one or very limited number of fonts used here. Where there is flexibility of font choice already I would want to leave close to 'as is' if at all possible.
Some may have noticed that I seem to "bounce around" from one area to the next without seeming to finish any entirely in one session. I get distracted by some details that poke out a bit more, so if I see something then I'll hammer it down. Its a whole lot of "down the rabbit hole" sort of a project, so I have to strictly limit my efforts to my free time _after_ work. When I adjust my EXTRA.css file at the forums, it is that same copy that I would validate again in my process of correcting poor CSS. Gee Wally the fonts really are big in some strange places... Thats okay Beav, its temporary fallout from other changes and I'm pretty sure the guy that done it is gonna fix it when he gets around to it. I also think a theme-mod for "extra large(r) fonts" is not a bad idea, it would be a bit more friendly than expecting those users who need, to zoom their view every time. *shrugs*
I suspect there may be other things modifying the font size. The supposed default font size in Firefox is 16px, is that what most everyone here has? Is the anomaly on my side and these fonts (as in this post) are not seeming to be rather large? Maybe I have to investigate how things are setup on forums.pcbsd.org in my themes there, to see if I've "missed a step" or something. The editor while I edit doesn't seem too large of text.
It certainly seems as if working on this theme will not be vastly simplified/consistent until after I heavily modify the structural templates involved. I happened to notice that the view a guest (not logged in) may get has a few issues. Just finished cleaning up the "sign up now!" button. There is always some other thing to fix, some other area I may not yet have seen.. and when I do wander into it there is something odd there. I sort of guessed at what I was getting myself into, to create a new theme, but its just amazing that something that *could* be rather simple has been built to be so exceedingly complex.. but not forever! :D
