XHTML DocTypes
Jul 23rd
Here I will explain you how to set the Document Type Definition (DTD) of an XHTML web-page. The DTD tag goes at the start of your coding before the starting html tag. There is no end tag or self-closing for the DTD tag.
There are 3 Doctypes usable by an XHTML document. Strict, Transitional, and Frameset. The doctype is used when validating an XHTML document’s content against a DTD to find markup errors. More >
IDs and Classes
Jul 18th
IDs and Classes can be mixed up a lot if you do not know what you are doing. You cannot use an ID more than once in an XHTML document or it renders the page invalid. A perfect use for this would be for a banner. Classes on the other hand were designed for to be used multiple times on a page. An ideal class would be for a content heading used numerous times.
Ending your tags in XHTML
Jul 5th
The thing with XHTML is many tags require to be closed that are not closed in HTML. An example is the <br> tag. In HTML it just looks like that, <br>. With XHTML on the other hand it must be closed. To close a tag like this add the / to the end. Now it looks like <br />. This is usually needed for codes without a </tag>. For example <div></div> does not require this.
Special Characters
Jul 5th
In XHTML your page will receive warnings from w3c for using improper methods of adding characters such at “©.” The simple and logical way to add this into our code is by simply using the alt code ALT+1069 or copy and pasting it into our XHTML document. This however is incorrect. Instead you must input ©. This method is necessary for many characters including everday things like the quote sign.
