<link> Element:

Purpose: Links external resources, such as stylesheets, to the HTML document.

Attributes:

rel="stylesheet": Specifies the relationship between the current document and the linked resource.

href="path/to/stylesheet.css": Specifies the URL of the external stylesheet.

Example:

<head>

<link rel="stylesheet" href="styles.css">

</head>

Other Options:

<style>: Used to embed internal CSS directly within the HTML document, not for linking external CSS.

<script>: Used to embed or link to JavaScript files.

<meta>: Provides metadata about the HTML document, not for linking stylesheets.

A developer needs to apply a red font color to the navigation, footer, and the first two of three paragraphs on a website.

The developer writes the following code:



Which CSS archives this developer's goal?

  1. Content
  2. Padding
  3. Margin
  4. border

Answer(s): A

Explanation:

To apply a red font color to the navigation, footer, and the first two of three paragraphs on a website, the correct CSS would use the content attribute to achieve the desired styling. However, the term "content" isn't correct in the given context. The appropriate answer involves directly specifying styles for these elements using CSS selectors.

Here's the correct CSS:

nav, footer, p.standard:nth-of-type(1), p.standard:nth-of-type(2) {

color: red;

}

CSS Selectors: The selectors nav, footer, p.standard:nth-of-type(1), and p.standard:nth-of-type(2) are used to target the specific elements. The nth-of-type pseudo-class is used to select the first and second paragraphs.

Applying Styles: The color: red; style rule sets the text color to red for the specified elements.

  2. Style

}

<div id="black">This text will be black.</div>
