CSS units
CSS has multiple units for expressing a length. Many CSS properties take “length” values, such as width, margin, padding, font-size, height, etc.
Example:
<!DOCTYPE html> <html> <head> <style> h1 { font-size: 60px; } p { font-size: 25px; line-height: 50px; } </style> </head> <body> <h1>This is heading 1</h1> <h2>This is heading 2</h2> <p>This is a paragraph.</p> <p>This is another paragraph.</p> </body> </html>
