CSS properties need to be separated by semicolons. Check for the missing semicolon between properties.
In the example below, a forgotten semicolon before the content property makes the CSS parser unable to understand the properties:
<style>
nice {
z-index: auto

<style>
nice {
z-index: auto;
content: "";
display: block;
}
