As a web developer, you know that linking CSS to HTML5 is essential in creating visually appealing and professional-looking web pages. There are three ways to add CSS to HTML5: inline, internal, and external. The most common way is to use external CSS files , which can be linked to HTML using the link tag and href attribute. The @import rule can be used to import CSS files , and alternate style sheets and media types can also be specified when linking CSS to HTML5.

In this article, we will provide a comprehensive guide on linking CSS to HTML5, including step-by-step guidance, real-life examples, and best practices for each method.

External CSS Files

The most common way to add CSS to HTML5 is by using External CSS Files . To link external CSS files to HTML5, use the link tag with the rel and href attributes. The rel attribute should be set to “stylesheet” and the href attribute should specify the path to the CSS file.

link rel="stylesheet" href="style.css"> 

• Keep CSS styles in separate files for easier maintenance.
• Use descriptive and meaningful file names.
• Place the link tag in the head section of the HTML document.

Inline and Internal Styles

Inline styles are used to apply CSS styles to individual HTML elements. Internal styles are used to apply CSS styles to the entire HTML document. To use inline styles, add the style attribute to the HTML tag and specify the CSS rules within the attribute value. To use internal styles, add the style tag within the head section of the HTML document and specify the CSS rules within the tag.

p style="color: red;">This text is red.p> head> style> p  color: red; > style> head> 

Best practices for using inline and internal styles include:

• Use inline and internal styles sparingly as they can make the HTML code harder to read and maintain.
• Use external CSS files whenever possible.

The Link Tag and Href Attribute

link rel="stylesheet" href="style.css"> 

Best practices for using the link tag and href attribute include:

• Use descriptive and meaningful file names.
• Place the link tag in the head section of the HTML document.

The @import Rule

The @import rule is used to import CSS files into another CSS file. To use the @import rule, specify the path to the CSS file within the CSS file that is importing it.

Best practices for using the @import rule include:

Alternate Style Sheets and Media Types

Alternate style sheets can be used to provide different CSS styles for different devices or user preferences. Media types can be specified to apply CSS styles to specific devices or media types. To specify alternate style sheets, set the rel attribute to “alternate stylesheet” and specify the title attribute to name the style sheet. To specify media types, use the media attribute within the link tag.

link rel="stylesheet" href="style.css" title="Default"> link rel="alternate stylesheet" href="print.css" title="Print" media="print"> 

Best practices for using alternate style sheets and media types include:

• Provide alternate style sheets for users with different preferences or devices.
• Use media types to apply specific CSS styles to specific devices or media types.

How To Add CSS

When a browser reads a style sheet, it will format the HTML document according to the information in the style sheet.

Three Ways to Insert CSS

There are three ways of inserting a style sheet:

External CSS

With an external style sheet, you can change the look of an entire website by changing just one file!

Each HTML page must include a reference to the external style sheet file inside the element, inside the head section.

Example

External styles are defined within the element, inside the section of an HTML page:

This is a heading

This is a paragraph.

An external style sheet can be written in any text editor, and must be saved with a .css extension.

The external .css file should not contain any HTML tags.

Here is how the «mystyle.css» file looks:

«mystyle.css»

body <
background-color: lightblue;
>

h1 color: navy;
margin-left: 20px;
>

Note: Do not add a space between the property value (20) and the unit (px):
Incorrect (space): margin-left: 20 px;
Correct (no space): margin-left: 20px;

Internal CSS

An internal style sheet may be used if one single HTML page has a unique style.

The internal style is defined inside the element, inside the head section.

Example

Internal styles are defined within the element, inside the section of an HTML page:

This is a heading

This is a paragraph.

Inline CSS

An inline style may be used to apply a unique style for a single element.

To use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property.

Example

Inline styles are defined within the «style» attribute of the relevant element:

This is a heading

This is a paragraph.

Tip: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly.

Multiple Style Sheets

If some properties have been defined for the same selector (element) in different style sheets, the value from the last read style sheet will be used.

Assume that an external style sheet has the following style for the element:

Then, assume that an internal style sheet also has the following style for the element:

Example

If the internal style is defined after the link to the external style sheet, the elements will be «orange»:

Example

However, if the internal style is defined before the link to the external style sheet, the elements will be «navy»:

Cascading Order

What style will be used when there is more than one style specified for an HTML element?

All the styles in a page will «cascade» into a new «virtual» style sheet by the following rules, where number one has the highest priority:

1. Inline style (inside an HTML element)
2. External and internal style sheets (in the head section)
3. Browser default

So, an inline style has the highest priority, and will override external and internal styles and browser defaults.

How to Link CSS to HTML – Stylesheet File Linking

Kolade Chris

HTML is the markup language that helps you define the structure of a web page. CSS is the stylesheet language you use to make the structure presentable and nicely laid out.

To make the stylings you implement with CSS reflect in the HTML, you have to find a way to link the CSS to the HTML.

You can do the linking by writing inline CSS, internal CSS, or external CSS.

It is a best practice to keep your CSS separate from your HTML, so this article focuses on how you can link that external CSS to your HTML.

How to Link CSS to HTML

To link your CSS to your HTML, you have to use the link tag with some relevant attributes.

The link tag is a self-closing tag you should put at the head section of your HTML.

To link CSS to HTML with it, this is how you do it:

Place the link tag at the head section of your HTML as shown below:

Attributes of the Link Tag

The rel Attribute

rel is the relationship between the external file and the current file. For CSS, you use stylesheet . For example, rel=»stylesheet» .

The type Attribute

type is the type of the document you are linking to the HTML. For CSS, it is text/css . For example type=»text/css» .

The href Attribute

href stands for “hypertext reference”. You use it to specify the location of the CSS file and the file name. It is a clickable link, so you can also hold CTRL and click it to view the CSS file.

For example, href=»styles.css» if the CSS file is located in the same folder as the HTML file. Or href=»folder/styles.css» if the CSS file is located on another folder.

Final Thoughts

This article showed you how to properly link an external CSS file to HTML with the link tag and the necessary attributes.

We also took a look at what each of the attributes means, so you don’t just use them without knowing how they work.
