Ionic v2 Button text in caps

Put the following in the variables.scss

    $button-md-text-transform: none;

By default, the value is uppercase for Android platform. Change it to none. This will be applied to every button in your app.

It seems the button has text-transform set to uppercase in CSS. Add the following CSS to your button: text-transform: none; to override the CSS property set.

Your code becomes something like this:

<button ion-button large block color="danger" style="text-transform: none;" (click)="openPage($event, 0)">
    This is my test Text.
</button>

You can use Platform Specific Styles to style the buttons in your application.

Ionic2 has four platforms:

1. ios: Viewing on an iPhone or iPad, mode = 'ios'.
2. android: Viewing on any android device, mode = 'md'.
3. windows: Viewing on any windows device, mode = 'wp'.
4. core: Any platform that doesn't fit any of the above platforms will use the Material Design styles, mode = 'md'.

Overriding the Mode Styles. You can use the class that is applied to the body to override specific properties in mode components. In this case you would like to override the button style to have no text transform.

Place the code down here in the variables.scss file. Scroll down untill you see the section "App iOS Variables" or "App Material Design Variables"

// Style Android buttons
.md button {
  text-transform: none;
}

// Style iOS buttons
.ios button {
  text-transform: none;
}

// Style Windows Phone buttons
.wp button {
  text-transform: none;
}
