    Default Config background image to fit the button

    Hi,

    I have a push button and set its iconCls: 'icon-myimage'. I define in the css file the icon-myimage class as below:

    Code:
    .icon-myimage{background-image: url(../icons/myimage.png); background-size: cover; height:auto; width:auto; max-width:100%; max-height:100%}
    The image displays very small in the button. I see in the debug window
    Code:
    .x-btn-default-small-icon .x-btn-icon {
    
    
    
    • width: 16px;
    • height: 16px;
    • top: 0;
    • left: 0;
    • bottom: 0;
    • right: 0;
    }
    I don't know how these classes are added automatically to my icon. If I disable width & height (16px) in the debug window then the icon fills up the button.

    I'm sure there is a way to config the css or in extjs javascript. Can somebody show me how to fix this problem? Thank you!

    Regards,

    Those classes are from the CSS that comes with Ext JS. Your classes need to come before or use the same classes as the default ones to override them.

    The button CSS is quite delicate, generally you'd just specify a background image and no-repeat for the icon.

    To set the icon size:
