Fluid Font Size with clamp() in CSS (2024)

FAQs

How to use CSS clamp for font size? ›

Here's a basic syntax for CSS Clamp: property: clamp( minimum, preferred, maximum ); For example, you can use clamp(16px, 5vw, 24px) for font size. This means the font size will be a minimum of 16 pixels, a preferred size of 5 viewport width units (vw), and a maximum of 24 pixels.

The clamp() CSS function clamps a middle value within a range of values between a defined minimum bound and a maximum bound. The function takes three parameters: a minimum value, a preferred value, and a maximum allowed value.

Fluid typography is a responsive typography technique where the text scales automatically with the screen size. As the screen size increases, the typographic values such as font size, line height, and letter spacing increase. Similarly, the values decrease when the screen size gets smaller.

Fluid sizing adjusts the width—and sometimes the height—of elements depending on the screen size.

Responsive Font Size

The CSS defines the font-size property of the h1 element when the viewport is at various breakpoints. For viewports up to 414 px wide, the font size is 16 px . For viewports between 415 px and 768 px , the font size is 32 px . For viewports of at least 769 px wide, the font size is 48 px .

Minimum font size is 36px (y1) Maximum font size is 52px (y2) Minimum value should end at 600px viewport width (x1) Maximum value should start at 1400px viewport width (x2)

Clamping can be used to adapt an input signal to a device that cannot make use of or may be damaged by the signal range of the original input.

The CSS font-size-adjust property may be used in situations where we need to retain the text's legibility while maintaining its aesthetic. The font-size-adjust syntax is as follows: number | none | initial | inherit; Number : The font-size-adjust property is set to a number.

Use em or px for font sizes

Printers have traditionally used those and similar units in preference to cm or in . In CSS there is no reason to use pt , use whichever unit you prefer.

Use Font Superfamilies

A font superfamily is a set of fonts designed to work well together. So, using different fonts within the same superfamily is safe. For example, the Lucida superfamily contains the following fonts: Lucida Sans, Lucida Serif, Lucida Typewriter Sans, Lucida Typewriter Serif and Lucida Math.

Em as CSS font size

If you don't have one set in the CSS, then 1 em will usually be equal to 16px, which is usually the default font size in browsers.

Well, font-size itself can be set in dynamic ways. For example, font-size: 10vw; . That's using “viewport units” to size the type, which will get larger and smaller with the size of the browser window. If we had max-font-size , we could limit how big it gets (similarly the other direction with min-font-size ).

To achieve that we only need one line of CSS: font-size: clamp(16px, calc(20px + (36–20) * (100vw - 768px)/(1920–768)), 48px); Here we use native CSS3 function clamp(), which accepts three arguments: the minimum value, the desirable value and the maximum value.
