Layout of sparkle4 images/text on Home page

Hi,

I have just upgraded a client's website from Joomla 3 to 4. The Joomla 3 site is at  robinsonot.com.au/ and the Joomla 4 site is at  robinsonot.com.au/j4/ .

Towards the bottom of the Home page content are three photos, each with text underneath linked to an article. These sit next to each other (one row, three columns) on the J3 website. However on the J4 site they sit underneath each other (3 rows, 1 column). I'm not sure if I have caused this with some change I made! Do you know how to rectify it?

Ideally I would like a 3 row/1 column arrangement on narrow screens such as smart phones, and a 1 row/3 column arrangement on large screens.

Many thanks,

Julia.

Hi again,

I have also lost the formatting of H3 headings in the black footer area (user1 to 4), plus the copyright line. Can you see how to fix this?

Thank you!
Julia.

So glad you took a while to reply. I have found my error (the omission of a single right brace) and resolved. Julia.
