Merging changes from Casper

I tried to leave all of the styles largely as they were. Most of the merges were pretty clean; however, these two selectors got a shadow added to them that I didn't know what to do with.

```css
 .blog-title {
      margin: 10px 0 10px 0;
      font-size: 5rem;
      letter-spacing: -1px;
 +    font-weight: bold;
 +    font-family: 'Open Sans', sans-serif;
 +    text-shadow: 0 1px 6px rgba(0,0,0,0.1); /* UPDATED FROM CASPER */
  }
  
  .blog-description {
      font-size: 1.8rem;
      line-height: 1.5em;
      font-weight: 300;
 -    font-family: 'Droid Serif', serif;
 +    font-family: 'Noto Serif', serif;
      letter-spacing: 0;
 +    text-shadow: 0 1px 3px rgba(0,0,0,0.15); /* UPDATED FROM CASPER */
  }
```
