How to change the font size in CSS
To change the font size in CSS, you can use the font-size property. The font-size property allows you to adjust the size of text within an HTML element.
Here’s an example of how to change the font size:
HTML:
<p class="custom-font-size">This is some text with a custom font size.</p>CSS:
.custom-font-size {
font-size: 20px; /* Replace with your desired font size */
}In this example, we have a paragraph element with the class “custom-font-size.” We target this element in CSS using the class selector .custom-font-size and use the font-size property to set the font size to 20 pixels.
You can use various units to define the font size:
px(pixels): Fixed size in pixels.em: Relative to the font size of the element itself.rem: Relative to the font size of the root element (usually the<html>tag).pt(points): 1/72 of an inch, typically used in print.%: Relative to the parent element’s font size.vw(viewport width): Relative to the viewport’s width.vh(viewport height): Relative to the viewport’s height.
Example of using different units:
.custom-font-size {
font-size: 24px; /* Font size in pixels */
}
.custom-font-size {
font-size: 1.5em; /* Font size relative to the parent element's font size */
}
.custom-font-size {
font-size: 1.2rem; /* Font size relative to the root element's font size */
}
.custom-font-size {
font-size: 20%; /* Font size as a percentage of the parent element's font size */
}Choose the appropriate unit based on your design requirements and how you want the font size to respond to different screen sizes and user preferences. The flexibility of CSS font sizing allows you to create responsive and accessible typography on your website.
