To link a CSS stylesheet to your HTML document, you need to add a line of code to your HTML file. This line of code is called a link tag.
The link tag is placed in the head section of your HTML document. You can see an example of this in the "Internal Stylesheet Example" section.
A common mistake is to place the link tag in the body section of the HTML document. This can cause issues with the styling of your webpage.

Ways to Insert
There are three ways to insert a style sheet, and understanding these options is key to creating effective external stylesheets.
External CSS is just one of the three ways to insert a style sheet, and it's a popular choice among web developers.
You can insert a style sheet externally by linking to it in the HTML document, which is a great way to keep your code organized and maintainable.

Internal CSS is another way to insert a style sheet, and it's often used for small projects or prototypes.
Internal CSS is inserted directly into the HTML document, which can make it harder to maintain and update.
Here are the three ways to insert a style sheet:
- External CSS
- Internal CSS
- Inline CSS
Inline CSS is the third way to insert a style sheet, and it's used sparingly due to its limited scope and potential impact on page load times.
Cascading Order
Cascading Order is a fundamental concept in HTML styling that determines which style will be applied when multiple styles are specified for an element. This happens when there's more than one style specified for an HTML element.
An inline style has the highest priority, and will override external and internal styles and browser defaults. This means that if you define a style directly in an HTML element, it will be used instead of any external or internal stylesheets.

The styles in a page will "cascade" into a new "virtual" stylesheet by following a set of rules. These rules have a specific order of priority, with the highest priority going to inline styles.
Here's a summary of the cascading order rules:
- Inline style (inside an HTML element)
- External and internal style sheets (in the head section)
- Browser default
This means that if you have an inline style, it will be used over any external or internal styles, and even over browser defaults.
Example
An external style sheet can be written in any text editor, and must be saved with a .css extension.
To create an external stylesheet, you can use any text editor you're familiar with, such as Notepad or TextEdit.
The external .css file should not contain any HTML tags.
This is an important distinction to make, as HTML and CSS are two different languages that serve different purposes in web development.
An external stylesheet can be linked to multiple HTML files, making it a convenient way to manage styles across a website.
By linking multiple HTML files to the same external stylesheet, you can ensure consistency in design and layout across your site.

Advantages and Disadvantages
Having an external stylesheet can be a real game-changer for your website's design and maintenance.
Improved maintainability is one of the biggest advantages of using external CSS. Having styles in a separate file makes it easier to manage and update your styles without modifying each HTML document.
External CSS also promotes enhanced reusability. The same CSS file can be linked to multiple HTML files, ensuring consistent design across your site.
Efficient caching is another benefit of external CSS. Browsers cache external CSS files, leading to faster page load times on subsequent visits.

Working with Style Sheets
Multiple style sheets can be used, but the value from the last read style sheet will be used if properties have been defined for the same selector in different style sheets.
If an external style sheet defines a style for an element, and an internal style sheet also defines the same style, the value from the last read style sheet will be used.
The order of the style sheets matters - if the internal style is defined after the link to the external style sheet, the elements will have the style defined in the external sheet.
However, if the internal style is defined before the link to the external style sheet, the elements will have the style defined in the internal sheet.

Customize Your Site
You can change the look of your site with CSS. It's easy and quick.
Using any of the methods above, you can add CSS to your website to match your brand's unique look and feel.
Note the correct way to write a CSS file name, such as "mystyle.css".
Don't add a space between the property value and the unit, like margin-left: 20 px;. Instead, use margin-left: 20px;.
Frequently Asked Questions
What is internal vs external stylesheet?
Internal styles are embedded within an HTML document, applying consistent styling to the entire page, while external styles are stored in separate files, allowing for global styling across multiple web pages. This distinction affects how you manage and reuse CSS code across your website.
