HTML issues tagged as semicolon.
Character references must always start with an ampersand (&) and end with a semicolon (;), for example the < character can be referenced as <.
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
content: "";
display: block;
}
</style>
Fix it by including the forgotten semicolon like this:
<style>
nice {
z-index: auto;
content: "";
display: block;
}
</style>
