This is not the correct syntax for CSS.
The style element in HTML is a means of inserting CSS into an HTML document directly, but CSS syntax is different from HTML syntax.
Inside your style element you can create selectors and apply properties to elements, using the syntax which is illustrated in the challenge description:
element {
property: value;
}
In this step you should apply a property of text-align with the value center to the h1 element. So, copy the syntax above and replace the words element, property and value with their corresponding values.
This is how you could add a CSS style to all p elements in your HTML document, which will turn the text colour red. You have a p selector, a color property and a value of red.
<style>
p {
color: red;
}
</style>
You should do something similar, except you should have an h1 selector, a text-align property and a value of center.
