What are HTML IDEs?

  • IDE – Integrated Development Environment
  • A software by which we develop and run HTML code easily
  • Examples:
    • Edit Plus
    • Visual Studio
    • Sublime text
    • Notepad++

Advantage of IDE:  Code intelligence – Giving ideas to programmer to develop the code more easily. For example, if we write start tag – IDE will write end tag automatically.

Case-sensitivity: Html is purely case insensitive; we can use lowercase, uppercase or mixed-case while we are writing HTML tags.
