What is the correct code php for 3-column layout of the home.php page (theme default), so that the article headers are automatically filled in blocks on the page?
Example screen, thanks!
You can get 3 columns with CSS3 and display: grid. For https://avcore.ru/ :
grid-template-columns: 1fr 1fr 1fr;
You need to do some little adjustements in home.php of your theme.
For more help, you can look at https://css-tricks.com/snippets/css/complete-guide-grid/ for example or look for css display grid on https://yandex.ru or https://google.com
