HTML tag marquee realizes various scrolling effects (without JS control)

The automatic scrolling effect of the page can be achieved by JavaScript, but today I accidentally discovered an HTML tag - <marquee></marquee> which can achieve a variety of scrolling effects without JS control.

The marquee tag can be used to move not only text, but also images, tables, etc.

Syntax: <marquee>...</marquee>; Description: Add the content to be scrolled between the tags.

Important properties:

1. Scroll direction (including 4 values: up, down, left and right)

Syntax: <marquee direction="scroll direction">...</marquee>

2. Scrolling behavior (scroll: scroll in a loop, the default effect; slide: scroll once and then stop; alternate: scroll back and forth alternately)

Syntax: <marquee behavior="scroll mode">...</marquee>

3. Scroll speed scrollamount (scroll speed is to set the length of movement each time you scroll, in pixels)

Syntax: <marquee scrollamount="5">...</marquee>

4. Scroll delay scrolldelay (set the scrolling time interval in milliseconds)

Syntax: <marquee scrolldelay="100">...</marquee>

5. Scroll loop (the default value is -1, the scroll will continue to loop)

Syntax: <marquee loop="2">...</marquee>

6. Scroll range width, height

7. Scrolling background color bgcolor

8. Blank space hspace, vspace
