A wealth of free web development tools is available for ensuring valid web design. Having a validated website means that clients and readers of the site will view it as the author intended, with cross browser functionality and seamless transitions from page to page. Following are a few of the most important web development validation tools to guarantee complete and error free code.
W3schools is a leader in web development instruction, offering easy to understand tutorials on mark-up languages, browser scripting and XML, as well as having a great website validator. W3Schools website validation tools include validation of site HTML, CSS, XHTML, XML and WML pages. Simply enter the URL of the website to be validated, and W3C will provide a full report of validation errors, listed chronologically with line and column numbers, as well as summations of the validation error for ease of location and correction.
For Firefox users, there are several useful add-ons targeted specifically at web development. Total Validator is a Firefox add-on that validates HTML and XHTML, checks for broken links, performs accessibility validation and provides a spell checker. It helps majorly in making the web page free from any errors.
Google Chrome and Opera also provides users with web development add-ons and widgets. Each of these browsers offer similar tools targeted specifically at their users. Google Chrome offers tools such as:
- Pendule – A multipurpose tool for developers and bloggers that includes solutions for style sheets, forms, images and accessibility.
- Fire Bug Lite – A web development debugging tool. The fire bug lite is available for both Firefox and chrome browsers, and the options provided by it helps a lot in different aspects of web designing.
- Validity – A simple HTML validator.

Opera offers web developers SDKs, or Software Development Kits. These kits include tools for development over many platforms and devices, from simple validation tools to tools for developing and debugging software. Opera also offers its users a site devoted solely to development called Dev.Opera.
