The <blockquote> tag is used for indicating block of longer quotation (i.e. quotation including multiple lines or paragraph). In simple term, it defines a block of quotation that is taken from another source. Mostly browser indent the text from both left and right with white space margin (5 spaces) and this tag renders with paragraph breaks. It is used only for long quotations, if you need to use short quotes then you can use <q> tag. You can use multiple <blockquote> tag in your web page. This tag must have start<blockquote> tag and end </blockquote> tag. If you don't want to use blockquote tag, you can use css in place of blockquote tag. See in below code and output.
