Continuing the discussion from We need a "large fonts" and "small fonts" theme to ship with Discourse:
Our themes now support dark/light/{any-color-scheme} toggles as well as variable font sizes 
But user interface for changing these settings is currently very basic:
We should have something closer to this (from GitBook):
I don’t have access to my usual image editor so here’s a cruder mockup than usual:
I think the <big> fix ruined it…
It shouldn’t have ruined anything except scaling for <big> and <small> tags, which should be avoided because they’re obsolete specifications that can be removed at any moment. <big> specifically is very bad because it will nest and scale infinitely if defined with ems.
I can probably change the <big> definition to a rem unit to prevent the exploit and allow at least some scaling based on the root font-size, but it still should be considered as relevant as the <blink> tag.
The plan has always been to add “user selectable theme components”
That means you can also flag “components” as selectable by end users. This would be done here:
Note, that screen shot is a “theme”, not default behaviour. My user selectable theme hamburger thingy ™ would have to be expanded to support this.
I suspected that might be a prerequisite for this feature.
Wouldn’t we want this front end widget (in particular the font sizer, which is a key accessibility feature) to be a default feature for every theme? So either (a) it should be bundled into core somehow, or (b) that theme component would be a default for all themes somehow, but the former sounds a lot easier to me.
I like this so much it hurts. Having a drop-down for each set of selectable theme components would make it a much cleaner presentation for the user. This is extreme granted, but instead of having a single dropdown with:
Standard Theme (Light w/ Normal Font)
Standard Theme (Light w/ Large Font)
Standard Theme (Dark w/ Normal Font)
Standard Theme (Dark w/ Large Font)
Standard Theme (Other Color Scheme w/ Normal Font)
Standard Theme (Other Color Scheme w/ Large Font)
Sam’s Simple Theme (Light w/ Normal Font)
Sam’s Simple Theme (Light w/ Large Font)
Sam’s Simple Theme (Dark w/ Normal Font)
Sam’s Simple Theme (Dark w/ Large Font)
Sam’s Simple Theme (Other Color Scheme w/ Normal Font)
Sam’s Simple Theme (Other Color Scheme w/ Large Font)
Material Design Theme (Light w/ Normal Font)
Material Design Theme (Light w/ Large Font)
Material Design Theme (Dark w/ Normal Font)
Material Design Theme (Dark w/ Large Font)
Material Design Theme (Other Color Scheme w/ Normal Font)
Material Design Theme (Other Color Scheme w/ Large Font)
Vincent Theme (Light w/ Normal Font)
Vincent Theme (Light w/ Large Font)
Vincent Theme (Dark w/ Normal Font)
Vincent Theme (Dark w/ Large Font)
Vincent Theme (Other Color Scheme w/ Normal Font)
Vincent Theme (Other Color Scheme w/ Large Font)
etc…
You’d be able to have something like:
Can’t wait for this feature!
We’re still planning user-selectable theme preferences for the future, but per-user font size selection is now part of core:
これは完了しましたか？具体的には、テーマコンポーネント向けのユーザー設定が必要です。
シンプルさを保つため、短期的なロードマップから外しました。ただし、将来的に実施される可能性はあります。

素晴らしい、ありがとう！これの例があることは知っていたけど、見つけられなかったんだ。テキスト入力（チェックボックスじゃなくて）が必要になると思うけど、なんとかしてみせるよ。
