Definition:
DHTML is short for “Dynamic HTML”. Dynamic HTML refers to the code from which interactive web pages are made and which are modified as the user interacts with them.
Table of Contents
What is it for?
DHTML is a term that serves to designate a combination of new HTML language tags and new style and programming options. They allow us to generate more dynamic and animated websites, which offers greater interactivity on the part of the user than HTML versions.
It does not require the use of plugins such as Flash or Java . The term encompasses the functionalities available to web developers who use HTML, CSS, Document Object Model, and JavaScript technologies in combination.
Today the term is deprecated since everything that is done with JavaScript such as AJAX, animations, sliders, carousels, form validation, etc., is considered DHTML. Nowadays, practically all websites have dynamic elements.
Using DHTML
In short, DHTML allows developers the possibility to add effects to pages. Some of its possibilities are the following:
- Animate text and images in the document, regardless of the position or shape of the element (block or inline).
- It favors a section that automatically updates its content with the latest news, the phrase of the day, or some other data.
- Use a form that obtains user data, processes it, verifies it, and gives an answer without having to make another call to the server.
- Generating buttons with custom actions
DHTML and its importance in SEO
It is essential for SEO to pay attention to how some functionalities are going to be implemented. The google spider, also known as crawler, is responsible for analyzing our website.
It would be important to know if the contents that are being generated, such as pop-ups or tabs, are relevant to position or not, and if they appear hidden on the page or not or, also, if the contents loaded with AJAX are indexable.
Difference between DHTML and dynamic pages.
The term DHTML is not the same as a dynamic page. A dynamic page is the one generated by some server language, and can be built differently based on the parameters it receives. It differs from a static page in that it does not use programming, so it is always the same.
The primary difference is that while the DHTML is dynamic or changes the client the dynamic page is the server.
