@Monish_Khara The workaround I could see is aligning your flex block left, and playing with the padding to keep your images and text blocks centered. Is this what you would be looking for as a result?
Almost! But I’d like to keep the image and text block centered (see attached). Aligning left with flexbox aligns the text block with the left of the image.
A hacky approach to trouble shoot would be styling a RTE on a hidden page and get the elements looking how you want and then apply that class to the CMS item that gets populated
