display in a row - 3 images for laptop / 2 images for tab / 1 image for mobile

Hi Manoj,

I would recommend you using Generateblocks plugin to create the layout.

The Grid block of Generateblocks is responsive by default, you can choose how many columns to show on different devices.

Let me know if this helps :)

generatepress is the best thing to have happened to me post covid.

You are welcome!

Glad to hear that :)
