In CSS, the attribute selector can set styles according to the attributes and values of the element, providing more flexible style control. ①Basic usage: Select elements with specific attributes, such as input[type] to match all inputs containing type attributes; ②Exact match: Use = to match specific attribute values, such as input[type="text"] to match only the text input box; ③ Partial match: Use = (include), ^= (start), and $= (end), to match part of the attribute values, such as a[href="//m.sbmmt.com/m/faq/example.com"] to match anchors containing specific links; ④Combination match: match multiple attributes at the same time, such as inputtype=&qu

will-change is a CSS property that is used to inform browser elements in advance of possible changes to optimize performance. Its core function is to enable the browser to create layers in advance to improve rendering efficiency. Common values include transform, opacity, etc., and can also be separated by multiple attribute commas; it is suitable for non-standard attribute animations, complex component transitions and user interaction triggered animations; but it must be avoided abuse, otherwise it will lead to excessive memory usage or increased GPU load; the best practice is to apply before the change occurs and remove it after it is completed.

The main difference between display:none and visibility:hidden is whether the element occupies space and its impact on the layout. 1.display:none will completely remove elements, do not take up space, and the layout will be readjusted; suitable for permanent or dynamic hidden elements. 2.visibility:hidden makes elements invisible but still retain their space and the layout remains unchanged; suitable for situations where structures need to be stable. 3.display:none hides all child elements at the same time, while visibility:hidden can control the display status of child elements separately. When selecting, it is determined based on whether the element is expected to affect the layout.

To change the color of web page text, the most direct way is to use the color attribute of CSS. 1. Color can be set through color name, hexadecimal, RGB or HSL; 2. Different elements can be set separately, such as navigation links and paragraphs; 3. Flexible color matching is achieved through class selectors; 4. Note that the color attribute is inheritable, and the child elements will inherit the color of the parent element by default, and the style needs to be covered separately to avoid conflicts.

Using pure CSS to achieve the accordion effect can be completed through HTML and tags. The specific steps are as follows: 1. Use and tags to achieve the expansion and collapse function, with clear semantics and support barrier-free access; 2. Set details borders, inner margins and other styles through CSS to unify the appearance, and hide the default arrows; 3. Note that multiple panels cannot be expanded at the same time through pure CSS restrictions, so JavaScript needs to be introduced to implement this function. In summary, basic functions do not require JS, but complex interactions still require script support.

In CSS, the order of drawing elements is affected by a variety of factors. By default, the browser draws in the order of positioning elements in the background and border → text content → child elements. 1. The default drawing order does not follow the DOM structure completely, but follows the painting order; 2. The hierarchy consists of whether the same stacking context belongs to the same stacking context and whether a new stacking context is created (such as transform, filter, opacity).
