Challenge: Improve a Blog Article Design

The webpage displays an article, but the typography needs improvement. Apply the following changes:

1. Set the font family of the entire page to 'DM Sans', sans-serif.
2. Increase the line height of all paragraphs to 1.6.
3. Make the title bold.
4. Add slight letter spacing (2px) to the title.
5. Add a subtle text shadow to the title with:
   • horizontal offset: 1px
   • vertical offset: 1px
   • blur radius: 3px
   • color: gray

Do not modify the HTML.

• In the body selector, use the font-family property and set it to 'DM Sans', sans-serif.
• In the .content selector, complete with line-height.
• In the .title selector:
  • Use font-weight to make the text bold.
  • Use letter-spacing to add 2px spacing between letters.
  • Use text-shadow and remember it requires four values in this order: horizontal offset, vertical offset, blur radius, and color.
