Added custom coding to Dawn theme as a result Images are greyed out on Iphone 12 mobile

[oliviawaite]

The issue is: on iPhone 12 Safari and Chrome images/icons I adjusted code are appearing greyed out

I added custom coding to the Dawn theme to adjust icons in multicolumns to not appear hyperlinked... I also can't quite remember what other coding I may have added and therefore caused this issue.

The issue is: on iphone 12 Safari and Chrome images/icons I adjusted code are appearing greyed out. 

Can you please help with this?
