• About HTML, CSS, and JavaScript
HTML (HyperText Markup Language):
The standard markup language for documents displayed in a web browser. It works alongside technologies like Cascading Style Sheets (CSS) and JavaScript.
CSS (Cascading Style Sheets):
A style sheet language used to define the presentation of documents written in HTML or XML. CSS is a core technology of the web, enabling developers to customize the appearance of web pages.
JavaScript (JS):
A versatile programming language that powers web page behavior on the client side. As of 2022, 98% of websites use JavaScript, often alongside third-party libraries.
HTML is essential for structuring web documents (web pages), while CSS defines their appearance. Together, they form the backbone of web design.
HTML Editor makes it easy to read or edit HTML files stored on your iOS devices. Test your HTML/CSS code on the go or experiment with JavaScript code directly from your mobile device.
