10 Websites to Validate your Html, Css, Javascript, and Php Online


Validating a webpage (html, css, javascript, php, etc) fundamentally denotes the usage of a programme or an online service to verify that the webpage is free of errors. Html, css, javascript and php related errors occur every time and they shouldn't be neglected because even a single unclosed tag could ruin a full webpage.

Below is a list of ten online validators.

1. The W3C Markup Validation Service: This service is owned by the World Wide Web Consortium (a body whose primary objective is to regulate the world wide web). It examines the markup validity of html, xhtml and css web documents. They supports validation by URI, file upload and direct input.


2. FreeFormatter is a html/css validator that supports URL and direct input only and makes use of the doctype declaration to validate the document structure. Just like that of W3C, it details the position(s) of the error(s).

3. WDG HTML Validator is also a html validator, like W3C and it supports direct input as well as file upload and URL validation but with it's direct input having a defaulted document declaration, head, title and body tags.

4. Dr. Watson's site validator, apart from validating the html syntax of your website, it also checks for spelling errors, search engine compatibility, verifies link and image links, speed analysis and displays the source code of the validated site.

5. JavaScript beautifier beautifies and unpacks both html and javascript codes; supports only direct input like JSlint.

6. JSLint is an online javascript validating tool that does nothing but check the errors in the quality of your javascript. Only direct input is supported and it features tons of validation plugins available for download.

7. The Online Lint also supports javascript and html like JavaScript beautifier but adds URL input to it's features.

8. WriteCodeOnline.com test runs both javascript and php with a url encoder as added added feature. It only supports direct input.

9. PHP Code Checker performs a line-by-line examination of common mistakes and errors made in php syntax.

10. Php Syntax Check is almost like php code checker but it allows you to select the php version which your code is written in; online test running is also supported.
