Describe the CSS `tab-size` property
Article Introduction：The tab-size attribute is used to control the number of spaces displayed by tab characters in HTML. The default is 8. The common usage is to adjust the indentation of the code block. 1. Basic usage: Set pre{tab-size:4;} to make the tab appear as 4 space widths, supporting numbers or inherit values. 2. Usage scenario: When displaying code in the structure, adjust the tab indent to make the layout more compact and beautiful, such as setting precode{tab-size:2;}. 3. Notes: Mainstream browsers support but IE is incompatible; it only affects tab display and does not affect spaces; child elements need to be set separately, otherwise the parent settings will not be inherited. The rational use of this attribute can improve the text display effect, especially for code document typesetting.

What is the default VSCode theme path on Arch Linux?
Article Introduction：The default VSCode theme path is not directly exposed, and built-in themes are usually integrated into the application. If installed through pacman, the home directory is /usr/share/code, but the theme file is not stored separately in the "themes" folder, but is compiled into the application or loaded at runtime. The themes installed by the user are located in the ~/.vscode/extensions/ directory. Each theme has an independent folder and contains a .vscode-theme file. To view the path of the currently used topic, you can observe the loaded file path when switching topics under the Network tab through the developer tool (Help>ToggleDeveloperTools). Summarize:

What is the CSS :target pseudo-class used for?
Article Introduction：CSS's :target pseudo-class is used to match and style target elements in the page based on the URL's fragment identifier (last part). 1. It is often used to highlight the page area that users jump to through anchor links, such as highlighting the target section through background color or border; 2. It can be used for simple tab pages or accordion effects without JavaScript, and control the display and hiding of the target elements through display attributes; 3. It can combine transition to achieve smooth animation effects when target switching; 4. It only takes effect when the URL fragment matches the element id, and does not affect the browser's default scrolling behavior, and is not supported but elegantly downgraded in old browsers such as IE8 and below.

Can you apply a transition to multiple properties at once?
Article Introduction：The key to using one line of code to transition multiple attributes is to correctly use the abbreviation of transition attributes and pay attention to performance and compatibility. The specific methods are: 1. Use the all keyword to set the transition of all attributes uniformly, such as transition: all0.3sease; 2. Clearly list multiple attributes that need to be transitioned and set parameters separately, such as transition: background-color0.3sease, border-radius0.3sease; 3. Common application scenarios include button hovering effect, menu expansion/collapse and responsive layout switching; 4. Pay attention to avoid unnecessary attributes for transition, consider browser compatibility, and identifying them that cannot be passed.
