Text areas are little boxes you can type html in and it will appear written instead of what it should be
This is a colourful textarea but thats like that because I have css. But you can have a colour one with out css <textarea> text here </textarea>
Changing the width and height; <textarea rows=5 cols=30> text here </textarea>
Making it colourful; <textarea ROWS=5 COLS=15
style="background:COLOUR HERE"
style="font-family:FONT HERE"
style="color:FONT COLOUR HERE"
style="border style:solid">
text here</textarea>
And a textarea you can use HTML in; <ilayer name="scroll1">
<div id="scroll3"
style="width:100;height:75;
background-color:COLORHERE;
overflow:auto">
text here
</textarea></div>
