When it comes to website design standards and practises there are many aspects a developer needs to consider. This includes HTML, CSS, frameworks, responsiveness, compatibility across multiple browsers etc. Microsoft has released a new tool at the Internet Explorer Dev Center- Modern.IE. This tool detects common coding practices that may cause compatibility problems or prevent your users from getting the best possible experience on a webpage. You simply need to enter the website URL and it generates a report on the coding issues for that website.
Whenever possible the scanner suggest a fix or enhancement with web standards like HTML5 & CSS3. It’s not a complete checklist for coding the modern web but just a starting point so you can spend less time testing for IE and more time building what matters on the web.
It also provides info on what is missing, why it is important and how to get it done.
You can also download the report or share it from the web app.
