Trying to add code block, but full code is displaying

I'm trying to insert a code block into my website to show progress bar for donations, but when adding a code block and choosing CSS, the full code is showing up on my site instead of the progress bar it's supposed to be showing. Am I missing something in my code? 

Here is the code, for reference:

body {
  padding: 50px;  
}

.progress-bg {
    margin: 0 auto;
    width: 55%;
    height: 78px;
    border-radius: 10px;
  text-align: center;
    -moz-box-shadow:    inset 0 0 10px #ccc;
    -webkit-box-shadow: inset 0 0 10px #ccc;
    box-shadow:         inset 0 0 10px #ccc;
}

.progress-bar {
    height: 78px;
    border-radius: 10px;
    float: left;
    width: 50%;
    /* fallback */ 
    background-color: #1c314a; 
    
    /* Safari 4-5, Chrome 1-9 */ 
    background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#1c314a), to(#27425f)); 
    
    /* Safari 5.1, Chrome 10+ */ 
    background: -webkit-linear-gradient(top, #1c314a, #27425f); 
    
    /* Firefox 3.6+ */ 
    background: -moz-linear-gradient(top, #1c314a, #27425f); 
    
    /* IE 10 */ 
    background: -ms-linear-gradient(top, #1c314a, #27425f); 
    
    /* Opera 11.10+ */ 
    background: -o-linear-gradient(top, #1c314a, #27425f);    
}

.progress-bg h3.goal, .progress-bg h3.raised {
    font-family: Arial,sans-serif;
  font-size: 1.5em;
  font-weight: 600;
    line-height: 78px;
    margin: 0;
    padding: 0;
    text-align: center;
    display: inline;
}

.progress-bg h3.raised {
    color: #fff;
    padding: 0 25px 0 0;
}

.progress-bg h3.goal {
    color: #b2b2b2;
  text-align: center;
}

body .progress-bg h3.raised {
    -webkit-animation: fadein 4s; /* Safari and Chrome */
       -moz-animation: fadein 4s; /* Firefox */
        -ms-animation: fadein 4s; /* Internet Explorer */
         -o-animation: fadein 4s; /* Opera */
            animation: fadein 4s;
}

@keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Firefox */
@-moz-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Safari and Chrome */
@-webkit-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Internet Explorer */
@-ms-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Opera */
@-o-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

.progress-bg h3.goal {
    float: right;
    display: inline;
    padding: 0 25px 0 0;
  text-align: center;
}

body .progress-bg div {
    -webkit-animation: progress-bar 2s ease forwards;
    -moz-animation: progress-bar 2s ease forwards;
    -o-animation: progress-bar 2s ease forwards;
    animation: progress-bar 2s ease forwards;
}

@-webkit-keyframes progress-bar {
    from { width: 0%; }
    to { width: 20%; }
}

@-moz-keyframes progress-bar {
    from { width: 0%; }
    to { width: 20%; }
}

@-o-keyframes progress-bar {
    from { width: 0%; }
    to { width: 20%; }
}

@keyframes progress-bar {
    from { width: 0%; }
    to { width: 20%; }
}

Let us know how it goes.

Hi Creedon - thanks for the response. I do not have the "display source code" toggled on.
