Frequently asked questions
What does the sizes attribute do?
It tells the browser how wide the image will be shown at different viewport widths, so it can choose the best file from srcset before layout is done.
Which image widths should I generate?
Pick widths that match your layout and common screens, for example small, medium and large steps. More sizes help only if the images are used.
What happens if the sizes attribute is wrong?
The browser may pick a file that is too large or too small. Describe the real displayed width of the image at each screen size.
