My CSS code for `.header` and `.mtstyle` are now showing in my header when I preview. Nothing I have done has fixed the issue. This just started to happen. Thoughts? Also, is there a way to combine the `a:link` css into one line? Thanks.

```css
.header {
  position: absolute;
  height: 45px;
  right: 0;
  top: 0;
  left: 0;
  background-color: white;
}

.mtstyle {
  text-align: center;
  margin-top: 5px;
  margin-left:15px;  
}

/* unvisited link */
.mtlstyle a:link {
  color: #3399CC;
}

/* visited link */
.mtlstyle a:visited {
  color: #3399CC;
}

/* mouse over link */
.mtlstyle a:hover {
  color: none;
}

/* selected link */
.mtlstyle a:active {
  color: #3399CC;
}

.mtlstyle a:link {
  text-decoration: none;
}

.mtlstyle a:visited {
  text-decoration: none;
}

.mtlstyle a:hover {
  text-decoration: none;
}

.mtlstyle a:active {
  text-decoration: none;
}
```

```html
<div class="header">
  <div class="mtstyle">
    <div class="mtlstyle">
      <h1><a href="index.php">Title</h1></a> 
    </div>
  </div>
</div>
```
