The fact that every webdev carries around/trades personal "reset" stylesheets to undo everything the browser does by default is insane. It really highlights the disconnect between W3C and reality.
I think the fact that every webdev feels the need to override the user's agent and impose their own idea of what size a H1 should be is, well, kind of imposing. I might want to make H1 be 50 point comic sans. This should not matter to the web developer.
I don't understand how one can design a website that would survive arbitrary style changes. I think that is unrealistic, so the designer should expect all default styles to be standard. And if the user has too much free time to change the font size then it is their own problem; my suggestion is that they simply use reader mode and change the styles there.
I would like to remind that some time ago browsers allowed to change the default font size; it never worked well so Opera started to scale the whole page instead. Other browsers followed it.
Android browsers seem to repeat the same mistake by the way: they override developer's styles when the user changes font size in OS accessibility settings.
I mean, it's my computer. I should ultimately be in control of how a document renders. I might need larger text due to poor eyesight, or need to use a screen reader. Or I might just be irritated that the web developer just up and decided that light gray on dark gray text looked cool (it doesn't, it barely can be read). Or I might want to scroll with my keyboard because a mouse is painful to my RSI. If I go out of the way and set up accessibility settings, I would expect all applications on my device (including the web browser) to respect those settings.
It matters because we’re the one that has to deal with ticket when user complains that their tweaked-to-within-an-inch-of-its life system inevitably breaks the world.
The problem isn’t you per say, it’s the 5000 people that mis-follow some YouTube video because it looks cool without it actually understanding what they’re changing , how to undo it, or what the implications are.
Mozilla doesn't agree with you; if they thought that was true they wouldn't do the weird phased rollout to stable.
Although I agree with codedokode insofar as I don't see how the phased rollout in stable could possibly help. Hopefully they've thought of something I haven't otherwise it is silly.
You shouldn't but there are many sites that assume the default font is black and the default background is white. (I'm sure I forgot to set them myself.)
There are [to] many ways to set the font size. I don't even know which on is the correct choice, if there is such a thing.
Maybe not trying to control it is the best approach? How can one tell?
