Frequently Asked Questions about CSS
What is the Full Form of CSS?
CSS stands for Cascading Style Sheets. It is a style sheet language used to describe the presentation and formatting of a document written in HTML or XML.
What are the types of CSS?
There are three types of CSS which are given below:
- Inline CSS: Inline CSS contains the CSS property in the body section attached to the element.
- Internal or Embedded CSS: The CSS ruleset should be within the HTML file in the head section i.e. the CSS is embedded within the HTML file.
- External CSS: External CSS contains a separate CSS file that contains only style properties with the help of tag attributes.
How do I link an external CSS file to an HTML document?
Use the <link> element within the <head> section of your HTML document. Example: <link rel=”stylesheet” type=”text/css” href=”styles.css”>
What is the purpose of the ‘box model’ in CSS?
The box model is a fundamental concept in CSS that describes the layout of elements. It consists of content, padding, border, and margin, which collectively determine the size and spacing of an element.
How can I center an element horizontally and vertically in CSS?
To center horizontally, use margin: auto; on the element. For vertical centering, consider using Flexbox (display: flex; align-items: center; justify-content: center;) or Grid (display: grid; place-items: center;).
What is the difference between ‘margin’ and ‘padding’ in CSS?
Margin is the space outside an element, creating space between the element and its surrounding elements. Padding is the space inside an element, creating space between the element’s content and its border.
How do media queries contribute to responsive design in CSS?
Media queries allow developers to apply styles based on characteristics such as screen width, height, or device orientation. They are crucial for creating responsive designs that adapt to different devices and screen sizes.
What is the ‘float’ property used for in CSS?
The float property is used to push an element to one side and make the text flow around it. However, it is less common in modern layouts due to the availability of Flexbox and Grid.
What is the purpose of the ‘z-index’ property?
The z-index property controls the stacking order of positioned elements. It determines which elements appear in front when they overlap on the z-axis.
What is the ‘!important’ declaration in CSS, and when should it be used?
!important is a CSS declaration that gives a style the highest specificity, overriding other styles. It should be used sparingly as it can make the code less maintainable.
Explain the difference between ‘inline’ and ‘block’ elements in CSS.
Inline elements do not start on a new line and only take up as much width as necessary. Block elements start on a new line and take up the full width available.
