css background-image

  • Post the images somewhere so your question makes sense

  • Hello how do I do it ?? First time q I use stackoverflow

  • 1

    In addition to the media queries that the friend has already mentioned, it is interesting to have 2 images at least, but recommended 3. You use 1 for larger resolutions, another for medium ones and another for smaller resolutions, which is your case. This is because a full hd image with dimensions for a monitor, is very impaired in mobile phones, losing a lot of quality and even affecting the element that this is.

  • got I’ll try to make a smaller image, but I can change them with css by putting another backgroud-image in @media of the exact size q ??

  • @lelis419 Yes, just change the url path when you pass the background to the image you want to use in @media

You’re not setting the responsiveness in your CSS code, try adding this: 

// Small devices (landscape phones, 576px and up)
@media (min-width: 576px) { ... }

// Medium devices (tablets, 768px and up)
@media (min-width: 768px) { ... }

// Large devices (desktops, 992px and up)
@media (min-width: 992px) { ... }

// Extra large devices (large desktops, 1200px and up)
@media (min-width: 1200px) { ... }

And pass the code you want between the brackets, and set the min-widht according to the minimum pixels you want for that size.

  • then I had already tried to do what you said, but the result was the same, the image is still cut in mobile

  • Did you set other values when you posted to @media? Lower values?

  • then I did not define, but what values you refer, because the width is as 100% and the height in my view would not interfere in the point I want
