How to code for older browsers?

[joelwenzel]

Hi,

I'm creating a website (actually I've already created it) and it use a bit of DOM and CSS. How do I make it compatible with netscape 4.5 (right now it doesn't work with netscape 4.5)

What I mean specifically, is what do I have to do for compatibility issues?

Do I have to right <b class='something'> instead of <b class=something>?

Is there a way to comment out javascript DOM code that might not be compatible?

one approach that i've seen with javascript is to use branching based on tests for supported features.

for example...

if (document.layers)
{
  //code for browsers that support layers
}
if (document.all)
{
  //code for browsers that support the "all" syntax
}
if (document.getElementById)
{
  //code for browsers that support standard DOM
}

as far as css is concerned, i don't believe you need to worry about hiding incompatible css. if the browser doesn't support a given css implementation, it simply will ignore it. you do need to be concerned about how the page will end up looking, however, when an older browser doesn't support a css feature that you're using.

Thanks.

I like that branching idea...
