Default Marquee Settings

• Horizontal scrolling is the default behavior of the <marquee> tag. Any text defined as a marquee will slowly and continuously scroll from right to left.
  
  <marquee>Place your text here</marquee>
  
  The default width of a marquee corresponds to the width of its containing element; if it is not contained within anything, it will span the width of the entire page.
  
  

Controlling Marquee Movement

• The "behavior" attribute determines whether the marquee keeps scrolling from right to left, bounces back and forth or stops after reaching the left edge of the page. The following code will cause the marquee to bounce:
  
  <marquee behavior="alternate">Place your text here</marquee>
  
  While replacing "alternate" with "slide" will generate a marquee that slides the text into the page and stops once the text has reached the edge.
  
  Setting a "direction" attribute with a value of "right" will cause the text to scroll from left to right; the "direction" attribute also accepts values of "up" and "down", although either option will turn your horizontal marquee into a vertical one.
  
  The "loop" attribute accepts a numerical value and controls how many times the marquee will loop; after the marquee has reached the specified number of repetitions, the text within the marquee will disappear.
  
  

Other Marquee Options

• The "scrollamount" attribute accepts a value in pixels that determines the distance between successive displays of the scrolling text; the higher the number, the faster the marquee will scroll, although at higher values the text may appear to be jumping across the page rather than scrolling smoothly.
  
  <marquee scrollamount="20">Place your text here</marquee>
  
  The "bgcolor" attribute accepts either a simple color name or a hexadecimal color value; the color will be used as the background of the marquee.
  
  <marquee bgcolor="#FF0000">Place your text here</marquee>
  
  <marquee bgcolor="yellow">Place your text here</marquee>
  
  Lastly, the "width" attribute controls the width of the marquee and accepts either a value in pixels or a percentage, calculated based on the width of the marquee's containing element.
  
  

Considerations

• The <marquee> tag is not a part of standard HTML. Different browsers may not support certain attributes or not support the tag at all, which will lead to your website not displaying as you intended. Too many marquees can add visual clutter to a page and irritate your visitors; even a single marquee, if set at too fast a speed, may become almost unreadable. Lastly, links placed within a marquee can be difficult to click for users who are new to computers or suffer from mobility issues.
