Dynamic layout background

Flow
1

I’m trying to change the background image of a layout on a button click. I used following css rules to add a background initially and in the button click event I tried to override the css rules.

.appname .v-desktop {
      background: url(icons/material_wallpaper.jpg) no-repeat center center fixed;
      -webkit-background-size: cover;
      -moz-background-size: cover;
      -o-background-size: cover;
       background-size: cover;
}

Overriding code

[code]
private void setImage(String url) {
             Styles styles = Page.getCurrent().getStyles();
             styles.add(".appname .v-desktop {" +"background: url(icons/img.jpg) no-repeat center center fixed;"
             +"-webkit-background-size: cover;"
             +"-moz-background-size: cover;"
             +"-o-background-size: cover;"
             +"background-size: cover;}");
}
[/code]

It won’t work as expected. When I check the css rules from inspect element feature of the browser, css rules are overridden correctly. Any help

Hi,

can you store the image names in your css file? In that case, you should be able to get away with just changing the css class name with add/removeStyle.
