# Customising Launch Button

The appearance and caption in the Keyfax launch button can easily be modified by making changes to a CSS web resource. This CSS snippet is an *unmanaged* component, meaning that you can customize it.

Using Power Apps, locate the KeyNamics Solution and within it, the **Keyfax CSS** component:

<figure><img src="/files/QxP28V0tK93ACiJHfv34" alt=""><figcaption></figcaption></figure>

Clicking the item will display this pane:

<figure><img src="/files/cQsrGpbhVaEYZlLhqWy3" alt=""><figcaption></figcaption></figure>

Click '**Text Editor**' to see the CSS snippet:

<figure><img src="/files/rnXkz2XL0FRkBMdqD5WM" alt=""><figcaption></figcaption></figure>

Make changes as appropriate (maybe save a copy before making any changes, just in case!)\

Click **OK** then **Save** and **Publish**:
