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.
