Key points to remember: • CSS sets appearance rules for HTML • Targets elements, classes, and IDs • Rules wrapped in “curly brackets” { like this } body { background: white; font-family: Arial, sans- serif; } #head { background: black; color: white; } #content p { font-size: 14px; margin: 10px 0; } Crafting Custom CSS | @andymci | #PCTO152015-02-21 12
- 13. How They Work Together When your browser loads a page, it looks at the elements on the page and checks if there are CSS rules for those elements. Key points: • HTML uses id and class • CSS uses # and . • When we see id, we target with # • When we see class, we target with .
