How to Perform URL Encoding in HTML?

• HTML language creates URL using <a> tag and href attribute. For Example <a href=https://www.google.com/>. if you make any website and want to go from one page to another, then write the file name. <a href=”page1.html”>.

• URL does not hold space. It takes the place of the plus sign (+) or %20. In the form of the HTML page, space occurred in “input” text output, then plus sign shows. Indirectly space occurred in URL name then %20 shows.
• URL tag contain the uppercase letters(A- Z), and lowercase letters(a- z), decimal digits(1-9) and some special characters.

<a href=”my file.html”>
