More About XHTML
HTML is a programming language that every website uses to display content. In WordPress, you can edit any post using HTML coding.
XHTML is an improved version of HTML that integrates with JavaScript and CSS. With HTML, a website is displayed even with errors in its coding markup. By contrast, XHTML has much stricter error handling.
Every WordPress theme is written in XHTML, so it’s essential to learn this language to start creating or modifying themes and plugins. There are two basic parts to a WordPress theme: the XHTML page and the Cascading Style Sheet (CSS). The XHTML theme page generally contains a header, content, and footer.
