About HTML

HTML(Hyper Text Markup language) is the standard markup language for Web pages, was created by Berners-Lee in the year 1991. Almost every web page over internet might be using HTML.

Syntax help

Fundamentals

  • Any HTML document must start with document declaration <!DOCTYPE html>
  • HTML documents begin with <html> and ends with </html>
  • Headings are defined with <h1> to <h6> where <h1> is the highest important heading and <h6> is the least important sub-heading.
  • Paragrahs are defined in <p>..</p> tag.
  • Links are defined in <a> tag.

    Example:

    <a href="https://onecompiler.com/html">HTML online compiler</a>
    
  • Images are defined in <img> tag, where src attribute consists of image name.
  • Buttons are defined in <button>..</button> tag
  • Lists are defined in <ul> for unordered/bullet list and <ol> for ordered/number list, and the list items are defined in <li>.

HTML Elements and Attributes

  • HTML element is everything present from start tag to end tag.
  • The text present between start and end tag is called HTML element content.
  • Anything can be a tagname but it's preferred to put the meaningful title to the content present as tag name.
  • Do not forget the end tag.
  • Elements with no content are called empty elements.
  • Elements can have attributes which provides additional information about the element.
  • In the below example, href is an attribute and a is the tag name.

    Example:

    <a href="https://onecompiler.com/html">HTML online compiler</a>
    

CSS

CSS(cascading style sheets) describes how HTML elements will look on the web page like color, font-style, font-size, background color etc.

Example:

Below is a sample style sheet which displays heading in green and in Candara font with padding space of 25px.

body{
  padding: 25px;
}
.title {
	color: #228B22;
	font-family: Candara;
}

HTML Tables

  • HTML Tables are defined in <table> tag.
  • Table row should be defined in <tr> tag
  • Table header should be defined in <th> tag
  • Table data should be defined in <td> tag
  • Table caption should be defined in <caption> tag

HTML-Javascript

  • Javascript is used in HTML pages to make them more interactive.
  • <script> is the tag used to write scripts in HTML
  • You can either reference a external script or write script code in this tag.

Example

<script src="script.js"></script>
