Is there a way to hide a html code but still have it appear --I am trying to hide the code from bots is there any type of code to do this.

No, there is no way of doing that.
HTML don't allow anything like that.

Try a graphic. Might be able to modify the captcha script on my site (see sig -- then FAQ)

Write it onto the document with javascript

**JeremyMiller** · 05-09-2008, 08:39 PM

christhirst has the best suggestion!

Something like

HTML Code:

<script>
//For the codes to use for each letter, see http://www.asciitable.com/
document.write(String.fromCharCode(52,65,110,76,120));
</script>

This may help:

You can google for ways to obfuscate your code server side using php or client side using javascript. There are many many options and ways to do this. Remember though any method of obfuscating code can be cracked, but for a typical screen scraping bot you'll be okay.

Anything can be cracked or hacked except the one-time encryption pad. The method chrishirst suggested is the easiest to implement and does very well.

Mr. Miller and chrishirst are on the money.
example:

Putting this on your website:

HTML Code:

<script language="JavaScript" type="text/javascript">
var i,y,x="3c68746d6c3e0d0a3c686561643e0d0a3c7469746c653e526f6220697320636f6f6c3c2f7469746c653e0d0a3c2f686561643e0d0a3c626f64793e0d0a48656c6c6f20576f726c64210d0a3c2f626f64793e0d0a3c2f68746d6c3e";y='';for(i=0;i<x.length;i+=2){y+=unescape('%'+x.substr(i,2));}document.write(y);
</script>

is actually:

HTML Code:

<html>
<head>
<title>Rob is cool</title>
</head>
<body>
Hello World!
</body>
</html>

So when someone visits your site they will see Rob is cool in their browser. A bot will see nothing. But the downfall of that is search engine spiders will also see nothing.

What exactly are you trying to hide? If its a form, there are much better ways of preventing bots such as captcha (Completely Automated Public Turing Test to Tell Computers and Humans Apart) etc...
