// ------------------ Gradient Output --------------------
// Syntax for use:

// gradient(TEXT_STRING_HERE,HEXCODES_STRING_HERE);

// use in similar way you would use document.write();
// note, it cannot be used to return a string value.
// gradient() takes two arguements. the first will
// be the original pure text string. (no htmlcodes)
// the second argument is a string of color hexcodes
// seperated with spaces thru which the text should
// progress. for example say you wanted to print out
// the string "color gradient", and you wanted it to
// progress from blue to red. a color code for blue
// is 4444FF, and a color code for red is FF4444.
// taking those two codes, and the original string,
// somewhere in the body of the document you would
// write within a <Script> tag the following:
// gradient("color gradient","4444FF FF4444");
// if however, you wanted it to progress thru three
// or more colors, its as simple as adding them to the
// string of color codes. it is important to remember
// however that the string must be color HEXCODES, and
// not merely just color names, (e.x- "red", "yellow")
// if this seems like too much trouble, then perhaps
// you should try something simple like ripping off
// some annoying status bar text scroller. =Þ
// one last thing. if you overuse this script, i can
// pretty much gaurantee people will hate your webpage.
// the fact is, this javascript is memory intensive. if
// you overdo it, you're crashing some visitors' browsers.

Füge auch dieses Script mit ein. Hier kannst du deinen Text festlegen, sowie den Farbverlauf beeinflussen:

<SCRIPT language="JavaScript">
gradient("Hier könnte dein Text stehen...","FF0000 000fff 0000FF");
document.write('<BR>');
gradient("...in schicken Regenbogenfarben.","444444 DDDDDD 444444");
document.write('<BR><FONT size=+1><TT><B>');
gradient("Versuch es...","FF8888 FFFF88 88FF88 88FFFF 8888FF FF88FF");
document.write('</B></TT></FONT><BR><FONT size=2>');
gradient("und deine Homepage sieht super aus.","884488 444488 448888 448844 888844 884444");
document.write("</FONT><BR>");
</SCRIPT>
 

Hinweis: Wenn du dir hier die Quelltexte kopierst, dann füge sie am besten mit einen Texteditor in dein HTML-Dokument ein, da die meisten Webeditoren es als normalen Text interpretieren.
