The Basics


Getting to know web design

Web design is an amazing medium for self-expression, but its sheer complexity makes it challenging for many beginners and intermediate artist. You need to understand a lot of things to be able to do web design well.



HTML Example

<!DOCTYPE html>
<html>
<body>

<h1>My First Heading</h1>

<p>My first paragraph.</p>

</body>
</html>

Example Explained

  • The DOCTYPE declaration defines the document type

  • The text between <p> and </p> is displayed as a paragraph


What is HTML?

HTML is a language for describing web pages.

  • HTML stands for Hyper Text Markup Language
  • HTML is a markup language
  • A markup language is a set of markup tags
  • The tags describe document content
  • HTML documents contain HTML tags and plain text
  • HTML documents are also called web pages

HTML Tags

HTML markup tags are usually called HTML tags

  • HTML tags are keywords (tag names) surrounded by angle brackets like <html>
  • HTML tags normally come in pairs like <b> and </b>
  • The first tag in a pair is the start tag, the second tag is the end tag
  • The end tag is written like the start tag, with a forward slash before the tag name
  • Start and end tags are also called opening tags and closing tags

What is CSS?

  • CSS stands for Cascading Style Sheets
  • Styles define how to display HTML elements
  • Styles were added to HTML 4.0 to solve a problem
  • External Style Sheets can save a lot of work
  • External Style Sheets are stored in CSS files

Styles Solved a Big Problem

HTML was never intended to contain tags for formatting a document.

HTML was intended to define the content of a document, like:

<h1>This is a heading</h1>

<p>This is a paragraph.</p>

When tags like <font>, and color attributes were added to the HTML 3.2 specification, it started a nightmare for web developers. Development of large web sites, where fonts and color information were added to every single page, became a long and expensive process.

To solve this problem, the World Wide Web Consortium (W3C) created CSS.

In HTML 4.0, all formatting could be removed from the HTML document, and stored in a separate CSS file.

All browsers support CSS today.


CSS Saves a Lot of Work!

CSS defines HOW HTML elements are to be displayed.

Styles are normally saved in external .css files. External style sheets enable you to change the appearance and layout of all the pages in a Web site, just by editing one single file!
