# How to chnage backcolor of alert box in sencha?

I got an issue with the [alert box](https://www.mindstick.com/forum/117/problem-in-displaying-alert-box-in-asp-dot-net) of [sencha touch](https://www.mindstick.com/interview/23004/define-class-system-of-sencha-touch) control. Issue is: I would like to change [background color](https://www.mindstick.com/forum/12937/how-to-style-togglebutton-so-that-the-background-color-is-white) of alert box, I tried to implement [CSS](https://www.mindstick.com/forum/514/background-gradient-ie7-css-problem) but its not letting me to do it.

Is there any other way to change background color of alert box in sencha?

Hi Alex,

You can perform this task as follows:

***var msg = new Ext.MessageBox();\
msg.show({\
title: 'Hello World',\
msg: 'Testing code',\
buttons: [{text:'Sure',itemId:'Ok'}],\
style:'[background](https://www.mindstick.com/articles/65/how-to-change-background-color-of-tab-control-in-c-sharp)-[color](https://www.mindstick.com/articles/77/how-to-split-form-background-color-in-c-sharp):blue;'\
});***

I hope this code might be resolve your problem.
