Frequently Asked Questions — FAQs

What are CSS and HTML, and why are they important for web development?

CSS and HTML are the building blocks of web development. HTML provides the structure, while CSS adds style and design elements to the website. Understanding both is essential for creating effective and visually appealing websites.

What are the different ways of adding CSS to HTML?

There are three ways of adding CSS to HTML: Inline CSS, Internal CSS, and External CSS. Inline CSS is added directly to the HTML element, Internal CSS is added within the HTML file, and External CSS is added in a separate CSS file that is linked to the HTML file.

What is a CSS external style sheet, and how is it created?

A CSS external style sheet is a separate file that contains all the CSS rules for a website. To create a CSS external style sheet, you need to move all the CSS rules from the HTML file to a new file with the .css extension. Then, you need to add a reference to the external style sheet file in the HTML file.

What is a CSS class, and how is it created?

A CSS class is a set of styling rules that can be applied to multiple HTML elements. To create a CSS class, you need to define a class selector in the CSS file and add the styling rules for that class. Then, you can apply that class to any HTML element on your website.

What are the best practices for using CSS?

Some of the best practices for using CSS include keeping your CSS code organized and well-commented, using external style sheets to separate your CSS from HTML, using meaningful class and ID names, and using CSS resets to ensure consistent styling across different browsers.

What are some common issues with CSS, and how can they be fixed?

Some common issues with CSS include browser compatibility issues, conflicting styles, and specificity issues. These issues can be fixed by using CSS resets, avoiding inline styles, and using the !important rule sparingly.

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.
