HTML (HyperText Markup Language) is the base for building all web pages. HTML is written via using HTML tags which are enclosed in angled brackets. Eg. <p> is a paragraph tag.
All HTML tags have a start and end tag. Eg. <p> is the start tag for paragraph and </p> is the end tag for it.
HTML is not a case-sensitive language. In simple words, uppercase (capital letters) and lower case letters (small letters) have the same meaning when used in HTML. Also, HTML doesn't render whitespace characters (return, tab, space etc)
