Topics のスクロールバーが CSS のカスタマイズにより更新されない

サポート
1

Discourse のインストールで何か壊してしまったようです。スクロールしてもスクロールバーが更新されません。
つまり、インジケーターが「1/25」から「2/25」に変わりますが、残りの 23 件の投稿の間は「2/25」のままになります。また、トピックの URL も ...../<post_number> に更新されなくなります。

JavaScript コンソールには、奇妙なエラーメッセージが表示されます。

When I use the safe mode to deactive the theme modifications, it works well : https://discourse.mfc.bayern/safe-mode

Probably a script that breaks the timeline

5

actually it looks like it is a CSS breaking the timeline ! If I remove loading of https://www.mfc.bayern/assets/css/headerfooter-style.css then it works
Any hint how a CSS may break the timeline (which I assume is javascript based) ?

You you change the heights in the wrong place, it will break the JS that detects scrolling.

7

which heights ? searching for height in the CSS yiels 140+ results :frowning:

OK found it
html,
body {
height: 100%; }
