I have created a theme in which i have extended luma theme. Now in my new theme I want to add some custom css to overwrite some default css classes for that I added _extend.less inside
test/luma/web/css/source.
Inside _extend.less i added some classes like
.logo { display:none; }
I haven't added styles-l.less and styles-m.less inside my theme and default_head_block.xml.
Now when I run commands
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
and then after cleaning cache
php bin/magento cache:clean
my rules are not implemented and default css breaking too.
Please suggest me the solution..
