CSS (Cascading Style Sheets) is a style sheet language used for describing the presentation of a document written in HTML (Hypertext Markup Language). CSS is used to style web pages and make them look visually appealing. One of the most important properties of CSS is font-size. In this article, we will discuss font-size in CSS in detail.
Font-size is a CSS property used to set the size of the font in a web page. It is used to specify the size of the text in pixels, ems, rems, or percentages. The font-size property is used to set the size of the font for the entire document or for specific elements within the document.
The font-size property can be set using different units of measurement. The most commonly used units are pixels (px), ems (em), and rems (rem). Pixels are a fixed unit of measurement, while ems and rems are relative units of measurement. Pixels are used to set the font size to a specific number of pixels, while ems and rems are used to set the font size relative to the parent element.
The font-size property can be set for different elements in a web page. For example, the font-size property can be set for the body element to set the font size for the entire document. The font-size property can also be set for specific elements such as headings, paragraphs, and lists.
Here are some examples of how to use the font-size property in CSS:
To set the font size in pixels, use the following code:
<p style="font-size: 16px;">This text is 16 pixels in size.</p>
In this example, the font size of the paragraph is set to 16 pixels.
To set the font size in ems, use the following code:
<p style="font-size: 1.2em;">This text is 1.2 ems in size.</p>
In this example, the font size of the paragraph is set to 1.2 ems. The font size is relative to the parent element.
To set the font size in rems, use the following code:
<p style="font-size: 1.2rem;">This text is 1.2 rems in size.</p>
In this example, the font size of the paragraph is set to 1.2 rems. The font size is relative to the root element.
To set the font size for headings, use the following code:
<h1 style="font-size: 36px;">This is a heading</h1>
In this example, the font size of the heading is set to 36 pixels.
To set the font size for lists, use the following code:
<ul style="font-size: 16px;">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
In this example, the font size of the list is set to 16 pixels.
