Making a <hr> horizontal rule smaller

    hr {
      width: 75%;
      margin-left: auto;
      margin-right: auto;
    }

Giving a <div> non scrolling background

    #divName {
      padding-top: 50px;
      height: 500px;
      color: #fff;
      background-image: url("your_url.jpg");
      background-repeat: no-repeat;
      background-attachment: fixed;
      background-size: 100%;
    }

Try different values to see the how it affects the div and over in the html

<div id="divName" class="container-fluid">

Vertical alignment (for one line of text)

This can be of use in a CSS navigation menu. The key is to make the height of the menu and the line-height of the text the same.

.nav li{
     line-height:50px;
     height:50px;
 }

    }
