Unable to change submit button backgroun

https://jdrwebdesigns.com/wordpress/jobs/admin/

Here’s the link to the login form I’ve created in dreamweaver. Everything looks perfect in there. When i copy the html and css over into my worpress page I’m seeing that the page is still loading the preset submit button styles.

Im so confused at what the issue could be of why its not seeing my css code
Below I’ve targeted the style to the specific div (#login-box) but the page is still displaying the preset style. Any help would easy my headache on this one!

CSS PART
#login-box input[type=”submit”]{
width:100px;
float:right;
border-style:solid;
border:2px solid black;
color:white;
background-color:black !important;
}

HTML PART
<div id=”login-box”>
<form action=”” method=”post”>
<label>USERNAME
<input type=”text” />
</label>

<label>PASSWORD
<input type=”text” />
</label>

<input type=”submit” VALUE=”LOGIN” >
</form>
</div>
