Website Developers Tools

 go to previous menu go to front page

It took me ages to find these tools for testing a website. If you write your .html and .css files in Notepad (or the more useful Notepad++) rather than using Wordpress or similar, these tools will check the coding, page loading speed, security and many other aspects to get your website working well. If you view my coding, I hope you will find I have kept it fairly simple and easy to understand. Note that the links open in a new tab or window.
