Being able to style dissimilar aspects of your HTML page is an important skill for web designers and developers. To style your HTML web pages with font colors and sizes, you'll need to be familiar with CSS. To target font size specifically, you can utilize the CSS font-size property.

If you're looking for a way to change HTML font size using CSS, we take you lot covered. Let's dive in by starting with an introduction to the CSS font-size holding.

Understanding the CSS font-size Property

The font-size property in CSS is handy when you need to change the size of HTML text. You can employ this holding to modify the size of every slice of text on an HTML page or target specific elements to modify.

Targeting specific elements is usually recommended as you typically don't want everything to have the same size. Text that doesn't follow a visual hierarchy is hard to browse through and differentiate higher-level headings from low-level ones.

In simpler terms, don't corruption the font-size belongings. If you want a heading to stand out, at that place are different HTML heading tags for that. Check out our HTML essentials cheat canvass for different tags, attributes, and more along with explanations.

The CSS font-size property takes in two types of values: absolute and relative.

Accented length values (i.e. px) are stock-still while relative ones (eastward.g. em and ex) are flexible. For instance, for a font-relative unit like em, the size is usually determined past the parent element's font size. However, root-based font-relative units like rem are influenced past the root element's font size (<html>).

Each has its pros and cons, only in the essence of keeping things focused, we won't discuss them in this article.

How to Modify the Font Size of an HTML Element in CSS

You tin change the font size of HTML text by using some standard CSS syntax.

Starting time, specify the selector (the text yous wish to modify) and open some curly braces. Adjacent, enter the font-size property followed by a colon, specify the specific size you want your HTML text presented in, and close it off with a semicolon.

Here'south the syntax:

          CSS selector {
            font-size: value;
}

To go a better grasp on the concept, review the post-obit HTML boilerplate that has a few additional lines of code (a heading and a paragraph):

          <!DOCTYPE html>
<html lang="en">
            <caput>
            <meta charset="UTF-8">
            <meta name="viewport" content="width=device-width, initial-scale=ane.0">
            <meta http-equiv="X-UA-Compatible" content="ie=edge">
            <title>Simple HTML Page</title>
            <link rel="stylesheet" href="style.css">
            </head>
            <body>
            <h1>This is my get-go heading</h1>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
            </body>
</html>

If yous want to change the font size of the paragraph chemical element, you need to select information technology (via a class, tag, or id) and, using the CSS font-size property, set a custom value with your preferred units. In our instance, we'll utilize pixels (px).

          p {
            font-size: 18px;
}

Although inline CSS is generally not brash in large projects, you tin also utilize information technology to change the size of HTML text. Taking notes from the external CSS code to a higher place, we tin implement the same thing inline similar so:

          <!DOCTYPE html>
<html lang="en">
            <head>
            <meta charset="UTF-8">
            <meta name="viewport" content="width=device-width, initial-scale=1.0">
            <meta http-equiv="Ten-UA-Uniform" content="ie=edge">
            <championship>Simple HTML Page</title>
            <link rel="stylesheet" href="manner.css">
            </caput>
            <trunk>
            <h1>This is my first heading</h1>
            <p style="font-size:18px">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed practise eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
            </body>
</html>

Text in the p HTML tag volition now have a new custom size.

If you experience issues, outset past checking whether you lot saved the changes to your file (besides, brand sure yous link your CSS canvas to your HTML file). If you did, try using the inline method, then refresh the page.
