Are the pictures blurry in the mobile version?

Question

css

Any format. Png, svg (from png enveloped). Styles are normal. Although setting a fixed width height, at least do not set. From the picture, max 100px with resizing up to 80 is already blurring. How to fix it?

Answer 1

I use the picture tag, in it you can specify separately pictures for different screen resolutions. So for the mobile version, just make a smaller picture and upload it.
It's just that when you press large pictures strongly, it's clear that the quality is lost)
