changed jQuery Mobile's default icon set, work on browser, failed on device

Question

in my application, I changed the jQuery-Mobile\'s default icon:

icons-18-white.png

CSS:

.ui-icon,
.ui-icon-searchfield:after {
background-color:          


        

Answer 1

It turns out that iOS and Android phones deal with "icons-36-white.png", so you should include and change it as well.
