Article Introduction：Using CSS advanced selectors and combiners enables precise control of styles and reduces redundant code. The attribute selector matches elements through attribute values, such as input[type="text"], only selects the text input box; the pseudo-class selector filters elements according to state or position, such as tr:nth-child(even) to set the background color of even rows; the combiner connects multiple selectors, such as h2 p selects the first p element immediately adjacent to h2; the rational use of these selectors can improve the logic and simplicity of CSS.

Article Introduction：The ch unit in CSS represents "character unit", which represents the width of the character "0" in the current font. It is mainly suitable for width layouts based on text size, such as setting the input box width to suit a specific number of characters, creating responsive UI components that are visually aligned with the character width, ensuring that each character is arranged neatly in a code editor or preformatted text block; it performs best in monospace fonts, with 1ch equaling the width of any single character; but in proportional fonts, due to the different widths of each character, it may not be able to accurately align.
