Quark: How to change number of columns shown in blog item list

[joejac]

The problem in my inherited theme was caused when replacing Hero image with LightSlider Banner, I had a wrong line of code, the solution is described in this post.

CSS in Frontmatter in Mache theme Works but no in Quark Theme

Please be aware that in order to avoid problems with other parts of the page, like for example the blog summaries, this line should be eliminated from lightslider.html.twig: {% extends 'blog.html.twig' %} as explained in this post: https://discourse.getgrav.org/t/is-there-a-tutorial-on-how-to-replace-the-hero-image-for-the-lightslider-script-on-quark-themes-blog/17972 Regards.
