silverwind a96c73f979 Remove svg.svg class, restore .rss-icon (#24667) ... Fix regression from https://github.com/go-gitea/gitea/pull/24476 where the `svg.svg` class misaligns SVG icons across the site and streched buttons unintentionally in vertical height. Before (button 30.3px): <img width="157" alt="Screenshot 2023-05-11 at 22 09 42" src="https://github.com/go-gitea/gitea/assets/115237/0fd137ab-ab52-4cf8-afca-c45776d526d0"> After (button 30px): <img width="160" alt="Screenshot 2023-05-11 at 22 09 59" src="https://github.com/go-gitea/gitea/assets/115237/4b741f4b-0fd2-4fae-9bee-16a7deb098e8"> [vertical-align: middle](https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align) is not suitable to align icons to text because > Aligns the middle of the element with the baseline plus half the x-height of the parent. Example of `vertical-align: middle` from MDN: <img width="232" alt="Screenshot 2023-05-11 at 22 29 28" src="https://github.com/go-gitea/gitea/assets/115237/179fb756-85a1-4cab-8219-1a4958f333e2"> So I think the [existing](365bb77a54/web_src/css/svg.css (L3)) `vertical-align: text-top` is generally still the best bet: <img width="241" alt="Screenshot 2023-05-11 at 22 34 24" src="https://github.com/go-gitea/gitea/assets/115237/0cd6edf5-12c0-4bdb-8771-a900f5ba2d35"> Co-authored-by: Giteabot <teabot@gitea.io>		2023-05-12 10:23:53 +00:00
