The correct answer is: A. !important
The !important keyword is used to specify that a style should take precedence over any other styles that might be applied to the same element. It can be used with any CSS property, and it will override any other styles that have been set for that property.
The <style> element is used to define a style sheet. A style sheet is a collection of CSS rules that can be applied to HTML elements. The <style> element can be placed in the head or body of an HTML document.
The #id selector is used to select an element with a specific ID. The ID is a unique identifier for an element. It is used to target an element with CSS rules.
The @media at-rule is used to specify different styles for different media types. For example, you could use the @media screen at-rule to specify styles for screen devices, and the @media print at-rule to specify styles for print devices.
Here is an example of how the !important keyword can be used:
“`css
p {
color: red;
}
p.important {
color: blue !important;
}
“`
In this example, the p element will have a red color by default. However, if the p element has the class important, it will have a blue color instead. This is because the !important keyword overrides any other styles that have been set for the color property.
