The following five websites help developers and designers to validate websites and check the website code for any sort of error.

1. W3C Markup Validation Service

The W3C Markup Validation Service allows users to validate their websites by either providing a link to the HTML, XHTML, SMIL, and MathML file or by either uploading one in the same format, as mentioned before.

If you just need to check a specific part of code, you may manually punch in the code in the “Direct Input” tab to validate it. There are various options available such as the Character Encoding option, showing source, showing outline or cleaning up markup by HTML-Tidy that you can choose before clicking “Check” to validate the code.

2. FAE

FAE, short for Functional Accessibility Evaluator, is a clean, easy to use website that allows users to validate the websites and get a rating of many different factors such as – Navigation & Orientation, Text Equivalents, Scripting, Styling and HTML Standards.

The website also breaks down the HTML Standards into smaller subtopics such as Titles, Sub-headings, Navigation Bars, etc and gives you a rating. Any sort of bug/error adds to the rating under the “Warm” or “Fail” heading. FAE

3. Browser Shots

The Browser Shot is a nifty little website that allows web developers, and designers to check how their website looks on different browsers on various operating systems. This is something that every web developers need to do, but do not have the means to do it.

Using the service is easy. All you have to do is type in the URL of the website you want to check and tick the browsers that you want to see. Click “Submit” and you will see the a screenshot of the website for each browser. Browser Shots

4. Pingdom Tools

Pingdom Tools is an online website that allows web designers and developers to test the load time of a page, the DNS health for the server on which the website is being run on, and also the speed at which a website connects to the server (ping rate).

To test any of the following items, just visit the website, enter the URL link of the website in the URL-link box, and click “Test Now”. The website will automatically do the processing and display to you the required details you have asked for – Page load time, DNS Health or Ping Rate. Pingdom Tools

The W3C Link Checker is just like the W3C Markup Validation website; except that it is more widely used.

The W3C Link Checker allows developers to find any sort of issues in links, anchors, and referenced objects in a web page, CSS Style Sheet. To check for any errors, just provide the W3C Link Checker website with the link to your HTML or CSS style sheet file and click “Check”. It will then automatically do the required proof-reading of the document and display any errors in the document to you (if any). W3C Link Checker If you are a web developer then you should try out, and use these websites as they not only make your work more “bug” free but also improves the whole site browsing experience for the users.
