HTML - Case Sensitive

I apoligise for what may seem a basic question but I have built a very large website in HTML 4.0, which runs fine in both IE7 and Firefox 3.

Out of habit, I put the first letter of each name - folder, file, and image, in upper case.

I have been told, however, that I shouldn't have done that as it could cause problems with some browsers.

As there really is a very large number of folders, files, and images that I would have to change, and because the website works fine with IE7 and Firefox, I thought I'd ask what forum members know (or think).

I've looked in my book on HTML and searched the Internet but have not managed to find the answer anywhere.

Ok, I've never really heard of this before, but my boss wants me to set it up, against my better judgement.

basically, we're building a new site for a client, but he's got two domain names that he wants to use, and each one needs to go to a different home page.

Is it possible to set up a redirect for a site that can understand which domain name has been entered and then send the customer to the appropriate page? or better yet, set up a home page like normal, but redirect only if the secondary domain name is entered.

And how does this affect SEO?

The other way I can think of to do this involves hard coding some links and one person jumping back and forth between domain names durring a single visit. Either that, or duplicate the whole site and drop it in a sub folder.

Recently one heck of a lot of stuff about why you should use tabless layouts, but I have yet to find any reason to use tabless layouts, apart from their fashionable and W3C say so.

However I have found several not to use them. Let me start with a plain simple myth about:

Tabless layouts are more browser compatibly.

Right? I frequently seen Mozilla Firefox, and IE process tabless layouts in quite different ways. Yet every time I have seen a table based layout, virtual browser has processed it exactly the same. The only exception I have seen is a percentage height on a table.

Conitinuing on:

Positioning

Also has anyone here found with nested div's, a reliable way of positioning a nested div and still keeping firmly fixed to the parent? Ok, you can use the absolute position and make sure the div is within the area of the parent, what happens if you move or resize the parent div? I have yet to find of way of making sure the child stay in a position relative to is parent, apart from not using positioing at all. If their is a way of reliably positioning a div relative to its parent, then I would be very glad to know.
Fixing a 'div' to another div.

Secondly, if you got a multiple column layout, without using JS, I yet to see a way of fixing two or more divs to together to make sure that they are always the same height.

With a table layout, you just had three columns in the table, and they will be fixed together, no faffing about

Overflowing Content.

Anyone here ever had a content div nested in a parent div, What happens when the content divs hot taller than the parent. In a very large number of setups, the contents of the content will flow straight out the parent. To sort the problem out you resize the parent.

With a table, whats in the table stays in the table. I have yet to see it happen any other way.


This is how things are my experience, I have yet to see any article that tells any way of doing that completely avoids all of these problems. If you know a way of avoiding these problems please, if not, and I ask the question, what is the practical point of tableless layouts?

I am simply developing a HTML website page, on this page, there are two flag images(USA and Poland) which is used as a language selection of the page for users.

I am wondering, for this single web page development (without any backend system), is there any efficient way to implement the page localization(that's display the page in different language) based on the flag selection from user?

Thank you in advance for any help.
