Editor or IDE supporting django templates and HTML/CSS validation?

Question

Is there a IDE that supports editing django templates and that is able to validate HTML and CSS?

Requirements:

• be able to detect and highlight errors in CSS, example: forgot to close "}", or invalid css attribute
• be able to make it learn new css attributes (like css3 ones or browser specific ones) - we don't want to see them invalidating the css
• validate partial-HTML, like the one from inside django templates.
• has to run on Windows
• Python support (optional / bonus)

I know that there are many cool Python IDEs but I found none that can be used to edit and validate HTML/CSS django-templates.

PyCharm from IntelliJ.

You can use geany (http://geany.org/) that support html/css and allows you to define your own snippets (http://configer.net/config/show/geany-html-and-django-snippets/) for django template language.
