Fluid background image on browser resize

Question

I want to achieve the fluid background image effect that you can see in this webpage: http://217.116.9.130/test2.html (taken from zara.com)

If you resize your browser to the left the woman in the image goes left with your resizing. I've taken the code from zara.com but I suspect the effect is done by a language I don't know.

Does anyone know and can give a clue (or hand me a link) on how to do it using jquery, css, ajax or php?

Thanks a lot

}

Answer 3

For example, if your background image is contained in your body tag, then the CSS should contain the background image assignment and then include:

top: 0;
bottom: 0;
left: 0;
right: 0;

This way - when the window resizes - the background immediately changes with it. Same principle for providing an overlay for a modal dialog.

Answer 4

do a css styling

background-position: center center;

other options are

center top
center bottom
left top

etc...

Answer 5

There is just an onResize method used in Javascript so that when the browser changes then that changes the CSS for the background image's position.

Give the image an id: id="fullImage"

They then use javascript to manipulate the left:; css style.

As you resize left changes up and down.

This should do it:

var el = document.getElementById(fullImage),
width = window.innerWidth,
imageWidth = [width of image here];
window.onresize = function() {
  el.style.left = imageWidth - width + "px";
}
