Frequently Asked Questions (FAQs)

What is the difference between line height and leading?

Leading is a traditional typography term describing the vertical space between lines of text, originally the physical lead strips in print. In CSS, line height controls this spacing digitally. They are effectively the same concept in digital and print contexts.

Why is controlling line height important for readability?

Proper line height prevents lines from feeling too cramped or too spaced out, which can cause eye strain or difficulty tracking text, thus improving user comfort and comprehension.

Can I use unitless line-height values?

Yes, using unitless values like 1.5 is often recommended as it scales proportionally with the font size, maintaining consistent spacing across responsive layouts.

How does vertical rhythm affect layout design?

Vertical rhythm aligns the spacing of various text elements (headings, paragraphs) along a consistent baseline grid, creating order and harmony throughout the page’s typography.

Is this tool suitable for non-developers?

Absolutely! The intuitive interface makes it accessible for designers, content creators, and marketers looking to improve text presentation without heavy CSS knowledge.
