Hi
@deveny
Here is an example of some HTML you can paste in the source view of the General Message to get a background image:
```html
<style>
html body#SurveyEngineBody {
background: url('https://cdn.pixabay.com/photo/2017/01/26/21/32/background-2011768_1280.jpg');
}
</style>
Any authentication text can go here
```
Notice that I'm selecting the body by ID here. This is because it is more specific than just body, and specificity is what matters most in CSS. If trying to override styling, be specific as possible!
A good way to debug this is to open up the Inspect and go to the Elements tab. Find the `<body>` tag and click on it, and then look at the CSS that is attached to the body below. Find your CSS and it will probably be crossed out because it's overridden by other styling. Take a look at that styling and see what made it more specific.
!

A common way of ensuring you have the most specific CSS is adding `!important` to the end of the attribute, like this:
```css
#MyElement {
display: none !important;
}
```

Hope this helps!
