javascript - Maintaining Aspect Ratio with 100% Width & Height (Cropping Overflow in CSS) -

-

i'm working on full-screen background slideshow.

my question is: how can set image take full screen , maintain aspect ratio?

min-height , min-width work, not keep aspect ratio when both set. want image cropped full coverage of container.

diagram of problem

i believe need have 1 dimension fixed, , other auto; given image dimensions , view-port dimensions variable, i'm thinking need @ least 2 sets of css rules, , javascript calculate 1 should used. there simpler way this?

i've drawn diagram illustrating problem. dark colors original images. median colors desired effect. lighter colors desired overflow scaled image.

i'm working on ken-burns effect full-screen background. know have worry transitions, i'm hoping can handle after.

tutorial ken burns effect:
http://cssmojo.com/ken-burns-effect/

solved: maju introducing me background cover. changing images divs , changing javascript + css on ken burns code images divs worked well. script changes element class, have use maju's css way or change script.

if use images in css background-image, can set on element background-size. , if understand right, need like:

.background {    position: absolute;    top: 0;    right: 0;    bottom: 0;    left: 0;    background-repeat: no-repeat !important;    background-position: 0 0 !important;    background-attachment: fixed !important;    -webkit-background-size: cover !important;    -moz-background-size: cover !important;    -o-background-size: cover !important;    background-size: cover !important;  }
<div class="background" style="background-image: url(http://www.jurosko.cz/images/stackoverflow.png)"></div>

cover affect image in way cover whole element right aspect ratio.

there new css style, doesn't work in ie/me.

for reason recommend use divs background-image.
