I have an article section on the homepage which displays 3 Joomla articles in 3 columns. It looks fine on a laptop but on a mobile it all squashes the 3 columns together and look bad. I was expecting them to stack one under each other on mobile but they don't.
How can I make these articles responsive so they stack one under each other on a mobile phone?
