The text on my button is underscored. How do I change it: 
<!DOCTYPE html>
<html>
<head>
<style>

.button1:hover {
	transform: scale(1.1);
	background-color: red;
}

.button1{
background-color: #073763;
 display:inline-block;
 margin:0 0.3em 0.3em 0;
 box-sizing: border-box;
 text-decoration:none;
 font-weight: bold;
 text-align: center;
 transition: all 0.2s;
 color: white;
 padding:0.5em 3em;
 font-size: 2em;
 position: relative;
 left: 25%;
}

}

</style>
