Have you downloaded all the Web browsers to verify that a browser is compatible? Are you badly beaten to fix an incompatible code? 工欲善其事, its prerequisite, here dream for you to recommend 13 Web design Browser compatibility tool, please easily handle browser compatibility issues.
HTML and CSS Validation
First let's take a look at how to verify HTML and CSS. I should say that because I work on a Mac, I have a slight bias towards the Mac. Don't worry, there are still a number of platform-independent solutions.
In addition to validating your files, you should also be able to format your own code "HTML/CSS formatting instances and hints" is an article on such topics.
1, the authentication of the consortium-HTML
Perhaps most people know that online authentication services can be verified by linking addresses, uploading files, or submitting code directly. There are a lot of validation options, though a lot of the time you don't really need them.
2, the authentication of the consortium-CSS
You probably know that the consortium also has a CSS checksum service. Like the HTML validation service, this CSS version is more selective and allows for the verification of the URI as necessary, file uploads and direct submission code.
3, [Firefox] web development tool bar
The Web Developer toolbar extension for Firefox Web Page Development toolbar is very popular, has a lot of great features, and has a great HTML and CSS validation tool that you can quickly verify your current browsing of local file sites. He sends a URI or file to the consortium and displays the validation results in the new Options page.
You can also open the Verify display page to quickly view the HTML and CSS validation information without having to open a new tab page. It would be very helpful if you were developing a project. Not only HTML and CSS you can also verify more options.
4, [Independent browser] the Validator favelets
I use Safari browser as my main web browser, but Firefox has spoiled me, and it has powerful extension options such as Web development toolbars and Firebug. Safari Browser Web Inspector, a similar firebug tool, but not file verification.
A quick and easy way to cover almost any major browser to validate HTML and CSS is to use Favelets. Favelets is a bookmark fragment that adds additional functionality via JavaScript. The consortium offers several validation favelets, and I often use safari.
5, your development editor
Most editors provide a little validation tool. The editor coda and Cssedit that I use now provide validation tools.
