Hii,
I want to simply change the font size and height of the field labels and fields.
I try this way:
Code:
{
    ...
    layout:'form',
    itemCls:'SolPanelFont',
    ...
    items:[{
        xtype:'checkbox',
        fieldLabel:'selam',
        boxLabel:'merhaba'
    },{
        xtype:'textfield',
        fieldLabel:'selam'
    },{
        xtype: 'combo',
        fieldLabel:'selam',
        ...
    }]
}
itemCls:'SolPanelFont', :
Code:
.SolPanelFont{
    font-family:tahoma,arial,helvetica,sans-serif;
    font-size:11px;
    font-size-adjust:none;
    font-style:normal;
    font-weight:normal;
    line-height:normal;
}
And overriding following CSS rules:
Code:
/* Radio Button icin ayarlar    */
.x-form-text, .ext-ie .x-form-file {
    height:19px;
    line-height:18px;
}

.ext-ie6 .x-form-text, .ext-ie7 .x-form-text {
    height:19px;
    line-height:15px;
}

.x-form-field-wrap .x-form-trigger {
    height:18px;
}

.x-form-field {
    font-size:11px;
}
Is this the correct way of doing this?
