I had to incorporate HTML and CSS codes in my web build, to achieve a swivelling flash-card effect. The app prompted me to convert the duplicate into a list (which I thought would save me the job of manually editing the positioning and arrangements of the 6 items), but it turns out that editing the HTML code of one item automatically changes all items in the line, despite my choosing in the cell-block that the change in the block should not be for "All items".
How can I edit the HTML items in the list individually?
