HTML

HTML is the core of every website. It contains every element a page contains: images, paragraphs, titles and other tags. We have a free tutorial series that will help you get started learning this essential markup (not programming) language. The lessons contain articles about tags, tag attributes, a list of important tags, links or anchor tags, images, tables, forms, text formatting and characters.

Use the HTML tag list to find the correct use of each element or use the code generators and grab the markup with a minimum amount of clicks.

CSS

Cascading Style Sheets give the look of you web pages. They specify the color and size of each element. They position the sections on the page and specify other design attributes. They are placed in .css file extensions and linked to the documents. The CSS cheat sheet will give you an idea about what this really means and will help you easily generate the desired styles.

Make sure to check out our text shadow gallery, gradient generator, table styler, border creator, RGB color picker and others in the navigation.

JavaScript (JS)

Often confused with the Java programming language, the JavaScript or simply JS makes your site interactive. If you know HTML, CSS and JavaScript you can start developing simple online games. JS is used to validate forms before submitting, to animate slideshows, and to bring the site alive.

We have JS editor and compressor and even a blog about the topic. Check them out and use them on a daily basis to make your life easier.
