Hi I am using a CMS (content management system) that uses CSS to color the buttons and menu items.

I used Firefox developer to inspect the element and the button is labeled

```
<span class="cta-button cta-icon-left  cta-custom-color-0 cta-button-medium cta-button-nomocaption cta-button-nomosubcaption cta-button-nomoicon">

```

I believe 'cta-custom-color-0' is where the color is contained for the button.

I tried adding the following HTML snippet to the page

```
<style>
.cta-custom-color-0 {background-color: #8640a8;}
</style>

```

However it isn't changing the button color.

What is the correct CSS syntax to override the color with a style snippet?
