The neatest method is probably the linked one, but the other ones are convenient and quick in the phases of prototyping a web page. The embedded and inline methods do not require having a separate file. The inline method saves you the trouble of considering what CSS classes your document should have.

For a larger site, in which many web pages share the same styling, and in which the styling should be customizable by the user, the linked method is the only viable option.

In this tutorial, you will learn the difference between the three types of CSS styles: inline, external, and internal. We’ll also uncover the advantages and disadvantages of using each method.

What Exactly Is CSS?

Cascading Style Sheets (CSS) is a markup language responsible for how your web pages will look like. It controls the colors, fonts, and layouts of your website elements.

This style sheet language also allows you to add effects or animations to your website. You can use it to display some CSS animations like click button effects, spinners or loaders, and animated backgrounds.

Internal CSS

Internal or embedded CSS requires you to add <style> tag in the <head> section of your HTML document.

This CSS style is an effective method of styling a single page. However, using this style for multiple pages is time-consuming as you need to put CSS rules to every page of your website.

Here’s how you can use internal CSS:

Open your HTML page and locate <head> opening tag.
Put the following code right after the <head> tag

Advantages of Internal CSS:

You can use class and ID selectors in this style sheet. Here’s an example:
Since you’ll only add the code within the same HTML file, you don’t need to upload multiple files.

Disadvantages of Internal CSS:

Adding the code to the HTML document can increase the page’s size and loading time.

External CSS

With external CSS, you’ll link your web pages to an external .css file, which can be created by any text editor in your device (e.g., Notepad++).

This CSS type is a more efficient method, especially for styling a large website. By editing one .css file, you can change your entire site at once.

Follow these steps to use external CSS:

Create a new .css file with the text editor, and add the style rules.
In the <head> section of your HTML sheet, add a reference to your external .css file right after <title> tag:

Don’t forget to change style.css with the name of your .css file.

Advantages of External CSS:

Since the CSS code is in a separate document, your HTML files will have a cleaner structure and are smaller in size.
You can use the same .css file for multiple pages.

Disadvantages of External CSS:

Your pages may not be rendered correctly until the external CSS is loaded.
Uploading or linking to multiple CSS files can increase your site’s download time.

Inline CSS

Inline CSS is used to style a specific HTML element. For this CSS style, you’ll only need to add the style attribute to each HTML tag, without using selectors.

This CSS type is not really recommended, as each HTML tag needs to be styled individually. Managing your website may become too hard if you only use inline CSS.

However, inline CSS in HTML can be useful in some situations. For example, in cases where you don’t have access to CSS files or need to apply styles for a single element only.

Advantages of Inline CSS:

You can easily and quickly insert CSS rules to an HTML page. That’s why this method is useful for testing or previewing the changes, and performing quick-fixes to your website.
You don’t need to create and upload a separate document as in the external style.

Disadvantages of Inline CSS:

Adding CSS rules to every HTML element is time-consuming and makes your HTML structure messy.
Styling multiple elements can affect your page’s size and download time.

Conclusion

In this tutorial, you’ve learned the difference between the three types of CSS: internal, external, and inline. Here’s the recap:

Internal or embedded ⁠— add <style> tag in the <head> section of HTML document
External ⁠— link the HTML sheet to a separate .css file
Inline ⁠— apply CSS rules for specific elements.
