本人是CSS盲!

<TABLE cellSpacing=0 cellPadding=0 width=540 align=center 
border=0>
<TBODY><TR><TD align=middle>

<TABLE cellSpacing=0 cellPadding=0 align=center border=0>
<TBODY><TR><TD align=middle>
<MARQUEE scrollAmount=3 direction=up width=540 height=170>
<MARQUEE scrollAmount=3 direction=down width=540 height=170>

<TABLE style="FILTER: revealTrans progid:DXImageTransform.Microsoft.gradient(gradientType=0,startColorstr=blue, 
endColorstr=red)" height=170 cellSpacing=0 cellPadding=0 width=540 align=center border=0>
<TR><TD>
<MARQUEE scrollAmount=3 direction=down width=540 height=170>
<MARQUEE scrollAmount=3 direction=up width=540 height=170>

<TABLE style="FILTER: revealTrans progid:DXImageTransform.Microsoft.gradient(gradientType=0,startColorstr=red, endColorstr=blue)" height=170 cellSpacing=0 cellPadding=0 width=540 align=center border=0><TBODY><TR><TD style="FILTER: chroma
(color=#FF00FF)" vAlign=top align=middle>
<DIV style="FILTER: glow(color=yellow strength=6); WIDTH: 100%; COLOR: #ff00ff">
<FONT style="FONT-SIZE: 35pt; FONT-FAMILY: 华文新魏" color=#ff00ff><B>the End</B></FONT> 

<P></P></DIV></TD></TR></TBODY></TABLE>

</MARQUEE></MARQUEE>
</TD></TR></TBODY></TABLE>
</TD></TR></TBODY></TABLE>

</td></tr></table>

不理解这段代码中的：
style="FILTER: revealTrans progid:DXImageTransform.Microsoft.gradient(gradientType=0,startColorstr=red, endColorstr=blue)"
是什么意思。
不理解这个效果是如何实现的，
请帮忙用通俗的语言概述一下，谢谢！
