1 - Can you explain the difference between HTML and CSS?
HTML, or HyperText Markup Language, is used for creating the structure and content of a webpage. It consists of tags and attributes that define how the content is displayed on a webpage. On the other hand, CSS, or Cascading Style Sheets, is used for defining the visual appearance of HTML elements on a webpage. CSS allows web designers to separate the presentation of a webpage from its content, making it easier to make changes to the design without affecting the content.
2) What is the box model in CSS?
The box model is the basic structure of an element on a webpage in CSS. It consists of four parts content, padding, border, and margin. The content refers to the actual content, such as text or images, within the element. Padding is the space between the content and the border, while the border defines the outline of the element. The margin is the space between the border and the neighboring elements.
3) How do you center an element horizontally and vertically in CSS?
To center an element horizontally, you can use the “margin: 0 auto;” property, which sets the left and right margins to auto. This will center the element within its parent container. To center an element vertically, you can use the “display: flex;” and “align items: center;” properties. This will align the element to the center vertically within its parent container.
4) What is the difference between a class and an ID in CSS?
A class is used to style multiple elements with the same properties, while an ID is used to style a unique element. An element can have multiple classes, but it can only have one ID. Additionally, an ID can be targeted with JavaScript, while a class cannot.
5) What is a float in CSS?
A float is a CSS property that allows an element to be placed on the left or right side of its container. This allows other elements within the container to wrap around it. It is commonly used for creating columns in a webpage layout.
6) How do you make a responsive website using CSS?
A responsive website is one that adjusts its layout and design based on the size of the screen it is being viewed on. This is achieved by using media queries in CSS, which allow designers to specify different styles for different screen sizes. By using responsive units such as percentages and viewport units, elements can also adjust their size and position based on the screen size.
7) What is the difference between inline and block elements in CSS?
Inline elements, such as <span> and <a>, do not break the flow of text and are displayed in a line. They do not accept width or height properties and cannot have margins or padding. Block elements, such as <div> and <p>, break the flow of text and are displayed on a new line. They can have width and height properties and can have margins and padding.
8) What is a pseudo class in CSS?
A pseudo class is a keyword added to a selector that specifies the state or position of an element. This can be used to style elements based on user interactions, such as :hover, :active, or :focus. It can also be used to style elements based on their position, such as :first child or :last child.
9) What is the use of the z index property in CSS?
The z index property is used to control the stacking order of elements on a webpage. It specifies the order in which elements are stacked on top of each other, with a higher z index value pushing an element to the top of the stack. This is useful for creating layered designs and ensuring elements are positioned correctly.
10) How do you include a comment in CSS?
Comments are used to add notes and explanations to a CSS code for future reference. They can be included by using the /* */ syntax, with the comment written in between. Comments are not displayed on a webpage and are only visible in the source code.
