Remove all Classy CSS files at once

Hi there,

I'm currently developing a new theme for Drupal 8. I really like the markup of Classy, using classes like menu--main in the markup. Primarily, I'm just using Classy's markup and implementing my own CSS styles. So, often I need to remove Classy's stylesheets or overwrite styles. I know, that you can remove stylesheets one by one, by adding a line for each stylesheet in .info.yml file, like:

DRUPAL 8 AJAX Form in TWIG Template

I'm working on my first Drupal 8 site and I'm having trouble with the php ajax forms when I place them into twig templates.

For example, I'll access the form using the path and the ajax events will work.

When I access the form rendered on a twig template the ajax events won't fire.
To get the form in the TWIG template, I'm using a preproccess_html hook and loading the form with the drupal form builder.

My question is how do I get the AJAX events to fire when rendering my form in a twig template? Do I need to create a twig extension?

Video Embed Field for D8

I used the Video Embed Filed in D7

Now I am transposing (manually), the site to D8. The Video Embed Field seems not to be available in D8. Is there any alternative to include video-clips in a content type?

I'm on Windows10

thanks

Drupal8 rc1 version installation needs opcache enable

I installed the drupal8 rc1 version on server and getting the opcache enable issue. It is asking to enable the opcache first to proceed the installation . I figured it and solved it as :

Go to PHP configuration / php.ini file and add these two lines end of the page

[opcache]
zend_extension=php_opcache.dll
; Determines if Zend OPCache is enabled
opcache.enable=1

You can also increase the max execution time on php.ini configuration file. Default from 30 to 180.
max_execution_time=180
