To create responsive images using CSS, it can be mainly achieved through the following methods: 1. Use max-width:100% and height:auto to allow the image to adapt to the container width while maintaining the proportion; 2. Use HTML's srcset and sizes attributes to intelligently load the image sources adapted to different screens; 3. Use object-fit and object-position to control image cropping and focus display. Together, these methods ensure that the images are presented clearly and beautifully on different devices.

opacity is an attribute in CSS that controls the overall transparency of an element, with values ranging from 0 (fully transparent) to 1 (fully opaque). 1. It is often used for the image hover fade effect, and enhances the interactive experience by setting the opacity transition; 2. Making a background mask layer to improve text readability; 3. Visual feedback of control buttons or icons in the disabled state. Note that it affects all child elements, unlike rgba, which only affects the specified color part. Smooth animation can be achieved with transition, but frequent use may affect performance. It is recommended to use it in combination with will-change or transform. Rational application of opacity can enhance page hierarchy and interactivity, but it should avoid interfering with users.

Use the ::selection pseudo-element of CSS to customize the highlighting style when the web page text is selected to improve the aesthetics and unity of the page. 1. Basic settings: define background-color and color through ::selection, such as yellow background with dark gray fonts; specific elements such as p::selection can also be limited. 2. Compatibility processing: Add the -webkit- prefix to be compatible with Safari and mobile browsers, and the Firefox and Edge standards are well supported. 3. Pay attention to readability: Avoid excessive color contrast or too fancy, and should be coordinated with the overall design. For example, choose a soft blue base in dark mode to improve visual comfort. Reasonable use can enhance the texture of the interface, ignore details

Word-break and overflow-wrap (formerly word-wrap) do differently when dealing with long words or unbreakable content. 1. Word-break controls how to break lines of words in block elements, break-all forces long words to break, keep-all avoids breaking, suitable for Chinese, Japanese and Korean texts. 2. Overflow-wrap disconnects long words when necessary to prevent overflow, break-word makes the context more intelligent. 3. In usage scenarios, use word-break:break-all for code, and use overflow-wrap:break-word for user comments. 4. Pay attention to differences in browser compatibility and different mobile behaviors

The key to setting multiple background images for elements in CSS is to use comma separation and attribute order correctly. 1. Use the background-image attribute and use commas to separate multiple image addresses. The first image is displayed on the top layer; 2. Use background-repeat, background-position and other attributes to control the display method of each image, and the values of each attribute correspond to each image in order; 3. You can also use the background abbreviation attribute to define all parameters at once to improve code readability and maintenance; 4. Actual applications include buttons and icons, decorative borders, page title bars and other effects. You can master the corresponding relationship between the order and attributes and use them flexibly.

To beautify the beginning of a paragraph to enhance visual appeal, a common practice is to use pseudo-elements of CSS or manually style the document. In web development, p::first-letter can be used to set the first letter style, such as enlarging, bolding, and discoloring, but it should be noted that it is only suitable for block-level elements; if you want to highlight the entire first line, use p::first-line to add styles; in document software such as Word, you can manually adjust the first letter format or create style templates, and InDesign has a built-in "first-sinking" function suitable for publishing and design; when applying, you need to pay attention to details, such as avoiding complex styles affecting reading and ensuring compatibility and format consistency.
