Hi Sharon,

You use curly braces to set rules on different elements.

Imagine you want to make all headers the colour red, with css you would do something like this.

<style>

h1, h2, h3, h4, h5, h6 {

color:red;
}

</style>

So in your example it should look like this:

<head>
<style>
h1{
    color: blue;
}
</style>
</head>
<body>
<h1>Sharon Weathers</h1>
</body>

Hi Sharon,

Further to what Hugo has said, the curly braces are what seperate your selector (which is the element you want to style in your CSS and your actual style rule.

CSS style are structured like this,

selector {

keyword: value;

}

with each statement separated by a semi colon. The Significance of the curly braces {} is that they separate your rule from the selector and they are required. :-)

e.g. 

selector {

 keyword: value;

}



h1 {
  color: blue;
}
