HTML

1. HTML is the hypertext markup language

   • HTML describes the structure of a Web page. HTML consists of a series of elements. HTML elements tell the browser how to display the content. HTML elements are represented by tags. HTML tags label pieces of content such as "heading", "paragraph", "table", and so on. Browsers do not display the HTML tags, but use them to render the content of the page
     • tags control everything
   • HTML makes code possible

2. How to use HTML

   • All HTML documents must start with a document type declaration: <!DOCTYPE html>. The HTML document itself begins with <html> and ends with </html>. The visible part of the HTML document is between <body> and </body>.
   • HTML paragraphs are defined with the <p> tag
   • HTML headings are defined with the <h1> to <h6> tags. <h1> defines the most important heading. <h6> defines the least important heading
   • HTML links are defined with the <a> tag.The link's destination is specified in the href attribute. Attributes are used to provide additional information about HTML elements.

3. CSS

   • CSS stands for Cascading Style Sheets. CSS describes how HTML elements are to be displayed on screen, paper, or in other media. CSS saves a lot of work. It can control the layout of multiple web pages all at once. CSS can be added to HTML elements in 3 ways: Inline - by using the style attribute in HTML elements Internal - by using a <style> element in the <head> section External - by using an external CSS file The most common way to add CSS, is to keep the styles in separate CSS files. However, here we will use inline and internal styling, because this is easier to demonstrate, and easier for you to try it yourself.
   • An inline CSS is used to apply a unique style to a single HTML element. An inline CSS uses the style attribute of an HTML element. This example sets the text color of the <h1> element to blue:
   • An internal CSS is used to define a style for a single HTML page. An internal CSS is defined in the <head> section of an HTML page, within a <style> element:
   • An external style sheet is used to define the style for many HTML pages. With an external style sheet, you can change the look of an entire web site, by changing one file! To use an external style sheet, add a link to it in the <head> section of the HTML page

4. Tags

   • basically tags tell the website what to do when where why and how
