Anki add-on: HTML Colored-Section-, Details-, and List-Buttons

Adds a few buttons to the editor. Detail-Button [Shortcut: Ctrl + Alt + 1]: Wraps the selected text in an unfoldable detail-tag. If no text is selected, will create an empty detail-tag template. Known issues: Any other html-tags in the selection (bold, italic, colors, details...) will get deleted in the process. Colored-Section-Buttons [Shortcut: Ctrl + Alt + 2~5]: Wraps the selected text in borders and changes the background color. If no text is selected, will create an empty border with colored background. Known issues: Any other html-tags in the selection (bold, italic, colors, details...) will get deleted in the process. Using both details- and colored-section-tags at the same time: Since both buttons will delete any other html-tags in the selection (so they might delete each other), you will have to work from outside to inside. First color the main sections, than detail the main sections and continue doing so for the inner sections. List-Buttons [Shortcut: Ctrl + Alt + 6~7]: Wraps the selected text in a ordered or unordered list. If no text is selected, will create an empty list. Known issues: Any other html-tags in the selection (bold, italic, colors, details...) will get deleted in the process. Delete HTML-Button [Shortcut: Ctrl + Alt + 8] Deletes (nearly) all html from the selected text. If no text is selected, will first select all text. Clicking again will delete (nearly) all html form the field. Known issues: It cannot delete html-tags at the beginning of the field. If you have a field starting with "<details>...", those will stay. This has been written primarly for me and some friends. It has issues, but I it works fine for my purposes. Feel free to change whatever you dont like.
