Question 1

How to set min and max font sizes in FitText.js?

Accepted Answer

Use the optional second parameter in the fitText call, such as jQuery('#headline').fitText(1, { minFontSize: '20px', maxFontSize: '40px' }). This ensures text stays within specified bounds while scaling fluidly with the container width.

Question 2

Is FitText.js better than using CSS vw units for responsive text?

Accepted Answer

For full-width text, CSS vw units are simpler and more performant as they don't require JavaScript. FitText.js is better when you need ratio-based scaling relative to a container's width, not the viewport, but it adds jQuery overhead.

Question 3

Can I use FitText.js without jQuery?

Accepted Answer

The original plugin requires jQuery, but the README lists community-maintained non-jQuery versions, such as adactio's vanilla JavaScript version or Angular.js adaptations, which can be used in modern projects.

Question 4

Why is my FitText not working with hidden divs or tabs?

Accepted Answer

FitText needs the element's width to calculate size. Ensure the container has a width (e.g., using display: block or inline-block with width) and run FitText before any scripts that hide the element, as noted in the CSS FAQ.

Question 5

How do I adjust the compressor in FitText.js for smoother scaling?

Accepted Answer

Pass a number as the first parameter to fitText(). Higher values like 1.2 make resizing more aggressive, lower values like 0.8 make it less aggressive, allowing you to fine-tune based on design needs, though it's not pixel-perfect.

Question 6

What are good alternatives to FitText.js for modern websites?

Accepted Answer

For modern projects, consider CSS solutions like vw units, container queries, or plugins like BigText for exact fitting. Non-jQuery versions of FitText are also available, but evaluate if JavaScript is necessary for your use case.
