  • How to change the start number of an ordered list in HTML
    How to change the start number of an ordered list in HTML
    Yes, you can change the starting number of the ordered list by using the start attribute in the tag, for example, making the list number start from 5; 1. This attribute is only applicable to elements and accepts any positive integer; 2. It only affects the display number, not the list structure; 3. All mainstream browsers support it, HTML5 has re-supported this attribute; 4. It is often used to continue the list number of the previous part or match a specific document format; 5. You can also use CSS counters to achieve more flexible control, but the start attribute is simpler and sufficient to cope with most scenarios, so it is recommended to use the start="n" method first.
