Best Practice for Background Properties in Media Queries?

Hi all,

I was wondering what would be best practice, when it comes to resizing and re-positioning an image for tablet and mobile devices?

.main-header {
    background: #fff url('../img/bg.jpg') no-repeat center;
    background-size: cover;
}

I would assume something like:

@media only screen and (max-width: 800px) {

    .main-header {    
        background-size: ?
    }
}

Many Thanks, Tom

Konrad Pilch I've just noticed my issue, maybe it's not possible as the content within the div where I have the background image responds so the height of this section expands, which almost pixelates the image in question.

Oh , i remembered, maybe set 100% height and width and maybe theres something wrong with ur divs.

It really depends on the situation itself. There are many ways or rather, situations in which you resize the background image of an element. These determine how you want to 'handle' them inside a media query.

I find myself using background-size:100% auto; or the reverse (and many variations in percentage values) depending on the challenge at hand. I don't like when my images get stretched in both directions and lose their aspect ratio (which makes them look odd or warped).

It depends Also what's the purpose of the image. And you can resize it on the break points Too.
