## Merge PR

Merged #268 and #300.

## Feature

- Added **Dark mode** support, and can be switched by the button at \<header \/\>.
  Regarding the mode switch button, considering that the user is less likely to use it after use, it is put together with the link back to the home page and disappears after scrolling. In the future, you can put the same less frequently used search button or other helpful things here.
- Add **MathJax mathematical formula** support, and update related documents (#266).
- Added **Mermaid chart** support (#186).
- Add support for the personal information `sticky` of the homepage to scroll with the page (#202).
-Now you can set the category information of the corresponding article to be displayed on the homepage and article page (#188).
- It is now possible to hide the catalog of specific articles (#244).

## Change

- Adapt to Dark mode, adjust the spacing of text `padding`.
- For mobile, when scrolling to the top part of the page, add a dark background to the \<header \/\> part. Helps to avoid buttons being disturbed by page title information.
- The critical point of page scroll switching is selected as the junction of the header image and \<container \/\>.

## Optimization

- Add a fade-in and fade-out animation effect to the floating button.
- Add more configuration content for the timeliness of `outdated_threshold` articles. And keep the style sheet design consistent with the quote block part of the article.
- Add support for Hexo's `comments` property to the article. When set to `false`, the comment plugin will not be displayed for the article.
- When setting the post `sticky` property, the sticky icon will also be displayed.
- The Toc of the article page will be ready sooner.
- Optimize the configuration of Babel and Eslint.

## Fix

- When Algolia is enabled, the unprocessed icon content will no longer be displayed when the page has not been loaded.
- When opening the Algolia search interface, prevent page scrolling.
- Fix the alignment of social icon including Steam icon (#301).

## Chore

- Fixed the code format and indentation of all `.ejs` files in the `layout` directory.
- Use `const` instead of unnecessary `let` in the script file to make the code look more clever.
- Unify most of the CDN links as `cdn.jsdelivr.net`.
- Update third-party dependency packages including jQuery to fix compatibility issues; remove unnecessary or deprecated dependencies.
- Update the warehouse documentation and secondary development documentation.

## Known issues

In dark mode, when switching or refreshing the page, due to the reload of the `layout.ejs` file, the component \<div class="contain" \/\> will cause a short white screen. The expected situation is that in Dark mode, set its background color to dark before loading (such as \#121212)
