1. HTML Introduction
HTML is the standard language used to create and structure web pages defining the layout and appearance of content. It consists of various elements that instruct web browsers on how to display content such as headings, paragraphs, and links. Web browsers interpret these elements to properly render the page but do not display the actual HTML tags themselves.
2. HTML Basic
All HTML documents must begin with a document type declaration and are structured with tags like <html>, <body>, and others for content. Headings are defined using tags from <h1> to <h6>, paragraphs with <p>, and links with <a>. You can view the HTML source code of any webpage by right-clicking and selecting "View Page Source" or "Inspect" to see and edit elements.
3. HTML Elements
An HTML element is made up of a start tag, content, and an end tag, with some elements like line breaks being empty and not requiring an end tag. HTML elements can be nested which means one element can contain others; all documents consist of these nested elements. HTML is not case sensitive but its recommended to use lowercase tags for consistency and compatibility with stricter document types.
