TLDRLearn the basics of CSS, including inline, internal, and external styles. Understand CSS selectors, declarations, properties, and values.

Key insights

🎨CSS is used for website layout and design, as opposed to HTML which is used for creating the structure of a website.

🔢There are three main ways to add CSS styles to an HTML file: inline, internal, and external.

🖍️Inline CSS should be avoided as it mixes presentation and styling in the HTML code.

📝Internal CSS is better than inline CSS, but it's still not recommended as styles are limited to one HTML file only.

🌐External CSS is the most common and recommended way, allowing styles to be used across multiple HTML files.


What is the difference between inline, internal, and external CSS?

Inline CSS is applied directly to an HTML element, internal CSS is placed in the <style> tags within the HTML file, and external CSS is stored in a separate .css file and linked to the HTML file.

Why should inline CSS be avoided?

Inline CSS mixes presentation with HTML code, making it difficult to separate the two. It is also not scalable and not recommended for use in professional web development.

Can internal CSS be used in multiple HTML files?

No, internal CSS is limited to the HTML file it is included in. To apply styles to multiple HTML files, external CSS should be used.

Why is external CSS the recommended method?

External CSS allows for separation of presentation and HTML code, making it easier to maintain and update styles across multiple HTML files.

What are CSS selectors and declarations?

Selectors specify which HTML elements to style, while declarations include properties and values that define how the elements should be styled.
