inline-size

The inline-size CSS property defines the horizontal or vertical size of an element’s block, depending on its writing mode. It corresponds to either the width or the height property, depending on the value of writing-mode .

If the writing mode is vertically oriented, the value of inline-size relates to the height of the element; otherwise, it relates to the width of the element. A related property is block-size , which defines the other dimension of the element.

Try it

Syntax

/* values */ inline-size: 300px; inline-size: 25em; /* values */ inline-size: 75%; /* Keyword values */ inline-size: max-content; inline-size: min-content; inline-size: fit-content(20em); inline-size: auto; /* Global values */ inline-size: inherit; inline-size: initial; inline-size: revert; inline-size: revert-layer; inline-size: unset; 

Values

The inline-size property takes the same values as the width and height properties.

Formal definition

Applies to	same as width and height
Inherited	no
Percentages	inline-size of containing block
Computed value	same as width and height
Animation type	a length, percentage or calc();

HTML Font Size – How to Change Text Size with an HTML Tag

Joel Olawanle

When you add text to your HTML file with an HTML tag, you won’t always want the text to remain the default size. You’ll want to be able to adjust how the text displays in the browser.

In this article, you will learn how to change the text size with an HTML tag.

Before you proceed, it is essential to know that there is only one way we can do this: through CSS’s font-size property. We can use the font-size property through inline, internal, or external styling.

In the past, we could adjust text size within our HTML tag without using CSS. But that was before HTML5. Then we added text using the tag, which can take in an attribute of size as seen below:

This size attribute can take in value from 1-7 in which the text size increases from 1 to 7. But like I said, this has long been depreciated, and most people don’t even know it existed.

In case you are in a rush to see how you can change the size of your text, then here it is:

// Using inline CSS 
Hello World!
 // Using internal/external CSS selector

Suppose you are not in a rush. Let’s briefly dive right in.

How to Change Text Size With Inline CSS

Inline CSS allows you to apply styles to specific HTML elements. This means we are putting CSS into an HTML tag directly. We use the style attribute, which now holds all our styling.

We use the font-size property alongside our value to change the text size using inline CSS. This value can use any of your preferred CSS units such as em, px, rem, and so on.

 
Hello World!
 
Any text whose font we want to change
 

A perfect syntax would be:

How to Change Text Size With Internal or External CSS

The approach you use to change text size in internal and external CSS styling is similar, since you use a selector. The general syntax for this is:

The selector can either be our HTML tag or maybe a class or an ID. For example:

// HTML 
Any text whose font we want to change
 // CSS p

// HTML 
Any text whose font we want to change
 // CSS .my-paragraph

Wrapping Up

In this article, you learned how to change the font/text size of an HTML element using CSS. You also saw how developers did it before the introduction of HTML5.

Also, keep in mind that it’s always better to style your HTML elements using internal or external styling, as it offers a lot of flexibility compared to inline styling.

For example, you can make use of one CSS class for all your p tags rather than having to add inline styles to all your p tag elements.

Using inline styles is not considered best practice because it results in a lot of repetition – you cannot reuse the styles elsewhere. To learn more, you can read my article on Inline Style in HTML.

I hope this tutorial gives you the knowledge to change the size of your HTML text so you can make it look better.

HTML Font Style – How to Change Text Color and Size with an HTML Tag

Kolade Chris

When you code in HTML and add some text, you don’t want to leave it like that. You want to make that text look good.

And to do that, you need to change their appearance through the color and font-size properties of CSS.

In this tutorial, I will show you two different ways you can make your HTML texts look good.

Basic font-size Syntax

How to Change Text Size and Text Color in the HTML Tag

You can change the color and size of your text right inside its tag with the color and font-size properties. This is known as inline CSS. You do it with the style attribute in HTML.

In the HTML code below, we will change the color and size of the freeCodeCamp text.

It looks like this in the browser:

To change the size of the text, you’ll use the style attribute, and then set a value with the font-size property like this:

The text now looks like this in the browser:

If you are wondering what 4rem is, it’s a unit of measurement. It’s the same as 64 pixels, because 16px makes 1rem unless you change the root font-size ( html ) to another value.

To change the color of the text, you can use the style attribute, and then set a value with the color property:

This is what we now have in the browser:

Combining the font-size and color properties gives us this in the browser:

How to Change Text Size and Text Color in an External CSS File

You can also change the color and size of text in an external stylesheet. Most importantly, you have to link the external CSS in the head section of your HTML.

The basic syntax for doing it looks like this:

Now, to change the text size and color of the freeCodeCamp text, you need to select it in the stylesheet and apply the appropriate properties and values to it.

Remember this is our simple HTML code:

You can change the color and size of the text by selecting the element (h1) and assigning values to the color and font-size properties:

We have the same result in the browser:

Conclusion

I hope this tutorial gives you the knowledge to be able to change the size and color of your HTML text so you can make them look better.
