If I understood correctly, I did as you said. Created a div-block, superimposed on the block-links and made the opacity of the gradient for the div-block.
But smoothness with the tools of transforms is still impossible to achieve. I made the opacity 1158ms (on the transform panel) - this did not work.
Go to the online link again. I updated the site, taking into account your words
Thank you very much for the video! It really turned out to be very easy to do, @aaronocampo. But a new question arose: the block-link, to which I assigned the effect “grayscale” - makes the div-block have a color, according to this effect.
Because of this effect, the color on the hover becomes dark gray. Look again. Why?
