flashing code

[clif]

If the number in cells of column A is greater than the number in cells of column B, the cell in colummn A will be flashing in red colour. ( Cell A5> Cell B5 , the Cell A5 will be flashing in red colour.) Is it possible? :banghead:

Don't do it. Flashing is a very bad experience for most (all?) users, and may even be illegal (data accessibility regulations) in some places.
