Introduction to <form> and attributes The <form> element in HTML is used to collect user input and submit data to a server or process it with JavaScript. It’s essential for creating interactive features like login pages, surveys, contact forms, and more. What is a <form>?
Semantic tags: <header>, <nav>, <section>, <article>, <footer> Semantic tags in HTML give meaning to the structure of a web page, helping both developers and browsers (including assistive technologies like screen readers) understand the content and layout better. Here’s a breakdown of commonly used semantic tags:
The <head> section: title, meta tags, favicon The <head> element is a crucial part of every HTML document. It contains metadata—information about the page that isn’t directly displayed to users but is essential for browsers, search engines, and other tools.
