A simple method to achieve scrolling effect based on HTML tag marquee
The automatic scrolling effect of the page can be achieved by javascript, but today I accidentally discovered an html tag - A variety of scrolling effects can be achieved without js control.
Using marqueemarks can not only move text, but also pictures, tables, etc.
Syntax: ; Description: Add content to be scrolled between markers.
Important attributes:
1. Scroll direction direction (including 4 values: up, down, left and right)
Syntax: > ;
2. Scroll behavior (scroll: cyclic scrolling, default effect; slide: scroll once and stop; alternate: scroll alternately back and forth)
Syntax:
3. Scroll speed scrollamount (scroll speed is to set the length of movement per scroll, in pixels)
Syntax:
4. Scroll delay scrolldelay (set the scrolling interval in milliseconds)
Syntax:
5. Scroll loop loop (the default value is -1, scrolling will continue to loop)
Syntax:
6. Scroll range width , height
7. Scroll background color bgcolor
8. Blank space hspace, vspace
Code example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> </head> <body> <p> <marquee direction="up" behavior="scroll" scrollamount="1" scrolldelay="0" loop="-1" width="1000" height="50" bgcolor="#0099FF" hspace="10" vspace="10"> 指整个Marquee对齐方式; (2)behavior:设置滚动的方式: scroll:表示由一端滚动到另一端,会重复,缺陷是不能无缝滚动。 slide:表示由一段滚动到另一端,不会重复... </marquee> </p> </body> </html>
The above is the simple method (must see) of the HTML tag marquee that the editor brought to you to achieve the scrolling effect. That’s all, I hope you all like it~

HTML5 is the latest version of the Hypertext Markup Language, standardized by W3C. HTML5 introduces new semantic tags, multimedia support and form enhancements, improving web structure, user experience and SEO effects. HTML5 introduces new semantic tags, such as, ,, etc., to make the web page structure clearer and the SEO effect better. HTML5 supports multimedia elements and no third-party plug-ins are required, improving user experience and loading speed. HTML5 enhances form functions and introduces new input types such as, etc., which improves user experience and form verification efficiency.

How to write clean and efficient HTML5 code? The answer is to avoid common mistakes by semanticizing tags, structured code, performance optimization and avoiding common mistakes. 1. Use semantic tags such as, etc. to improve code readability and SEO effect. 2. Keep the code structured and readable, using appropriate indentation and comments. 3. Optimize performance by reducing unnecessary tags, using CDN and compressing code. 4. Avoid common mistakes, such as the tag not closed, and ensure the validity of the code.

H5 improves web user experience with multimedia support, offline storage and performance optimization. 1) Multimedia support: H5 and elements simplify development and improve user experience. 2) Offline storage: WebStorage and IndexedDB allow offline use to improve the experience. 3) Performance optimization: WebWorkers and elements optimize performance to reduce bandwidth consumption.

HTML5 code consists of tags, elements and attributes: 1. The tag defines the content type and is surrounded by angle brackets, such as. 2. Elements are composed of start tags, contents and end tags, such as contents. 3. Attributes define key-value pairs in the start tag, enhance functions, such as.
