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

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

  • Table caption should be defined in <caption> tag

HTML-Javascript

  • Javascript is used in HTML pages to make them more interactive.
