Specifies how the Marquee text should move.
[DEFAULT - Text enters on one
side of the screen and travels to the opposite side and
cycles repeatedly from where it started] Slide
[marquee enters from one side of the screen and comes to stop at
the opposite side] Alternate
[marquee bounces from one side of the screen to the other.]
For a long time, only Internet Explorer supported this element. Although
Netscape/Mozilla now supports it, it is not and likely will never be in
the standards, so its use is not recommended.
Many of the effects of this element can be replicated with Java or
where Marquee support is guaranteed, it does represent a MUCH more
compact method of representation to produce moving text than Java
code would be.
There is no direct way to control the speed at which a bit of
Marquee text travels. The SCROLLAMOUNT and SCROLLDELAY attributes must be
used in tandem to create this effect and their use is not intuitive.
If no WIDTH attribute is set for a MARQUEE element, it behaves like a
block-level element (linebreak before and after) and occupies 100% of the
containing element/window width. If a width is set, it behaves like an
Internet Explorer versions before 4.0 Beta 1 will not understand the
DIRECTION attribute values of UP and DOWN.
Nested MARQUEE elements do not behave well in Internet Explorer. Don't try it.
The use of block structures in MARQUEEs (such as BLOCKQUOTE) will be
ignored in IE versions 3.0x and below, while in IE 4.0 and above it makes
the marquee appear as a multi-line field.
Internet Explorer versions 2.0 and 3.0 supported an ALIGN attribute. It
specified where the text around the marquee should align vertically
relative to the marquee and supported values of "Top", "Middle" and
"Bottom". Version 4.0 and later do not support this attribute.
[Test]Scenario: MARQUEE is the only content of a table
cell and WIDTH attribute is not set for EITHER the table cell
or MARQUEE element: Internet Explorer 4.0 and above - cell width
defaults to 1 pixel.
Internet Explorer 2.0/3.0 - cell width defaults to the width of
the MARQUEE content.
Netscape 7.0+: For the BEHAVIOR attribute, the SLIDE value is not supported
Netscape 7.0+: For the BEHAVIOR attribute, the ALTERNATE value is rendered differently
than IE - In IE, the marquee starts at one side of the marquee box, already onscreen.
It then proceeds to the opposite side of the marquee box, until its leading content edge
reaches the marquee box edge, and then returns back the way it came. In Mozilla, the
marquee content starts offscreen, comes onscreen at one side, travels to the opposite
side, then goes offscreen before travelling back the way it came.
