- Merging Cells in HTML Tables: `rowspan` and `colspan`
- The most common rowspan and colspan properties are used to merge cells in HTML tables. 1. Use colspan when cells span multiple columns horizontally, such as table header merging; 2. Use rowspan when cells span multiple rows vertically, such as fixed identification data display; 3. Use rowspan and colspan at the same time to achieve complex structures, but pay attention to the matching of layout order and number of cells. To ensure that the total number of columns in each row is consistent, it is recommended to draw sketches first, implement them line by line, and use developer tools to check to avoid misalignment and maintenance difficulties.

- Implementing HTML5 Form Validation Techniques
- Form verification can be achieved through HTML5 built-in attributes, CSS feedback, JavaScript control and prompt optimization. 1. Use required, type, min, max, pattern and other properties to achieve basic verification; 2. Use the :valid and :invalid pseudo-classes to cooperate with CSS to improve user feedback; 3. Use JavaScript to achieve flexible control through checkValidity() and setCustomValidity() methods; 4. Optimize prompt information and consider old browser compatibility. Front-end verification needs to be combined with back-end verification to ensure data accuracy.
