In magento2.0.2(downloaded from magentocommerce.com), after installation I created a new theme under app/design/frontend/mypackage with theme.xml , registration.php , composer.json as per the documentation.And then I inherited the blank theme by copying the theme files from vendor/magento/theme-frontend-blank into mytheme folder. Everything was fine. Now, when I add some style in theme.less in web/css/source and compile it using grunt , the styles are getting applied. But when I edit some of the existing styles or when I created a new less file with some styles, the styles are not getting applied.

Someone kindly explain me the reason behind this.

After doing any changes when i run php magento setup:static-content:deploy at front it is showing error like

enter image description here

After any css file or js file change. You need to deploy those static files to your pub static files!

So follow this steps-

  1. Go to var folder and delete view_preprocessed folder
  2. Also delete theme locale folder located in pub/static/frontend/spacename/themename/
  3. Now from your magento root run php bin/magento cache:flush & php bin/magento setup:static-content:deploy

Now your new files are ready!

  • can i use grunt clean to delete locale file in pub/static/frontend/spacename/themename/
