Let’s start reading,
- What is HTML?
The term HTML stands for HyperText Markup Language. This refers to the standard programming language applied to build and design robust and responsive web pages. HTML employs a large system of attributes and tags to highlight the creative layout and structure of a web page. This makes it possible for developers to add visually appealing images, links, texts and more elements as well.
- What do you mean by HTML tags?
The basic and most important building blocks of HTML are referred to as HTML tags. If you want to define the content and structure of your web page, HTML tags are the only thing you need. Each tag serves different purposes, such as developing paragraphs, links or catchy headlines. Tags are generally combined with an ending and a closing bracket. Let’s get to know how they look: <tag> and </tag>
- Explain HTML Attributes.
The HTML Attributes offer extra details related to HTML elements. These attributes are always defined at the beginning of the HTML tag of a component and typically highlighted in pairs like value or name, for example, name=”value”. HTML attributes are generally applied to develop stunning properties such as colour, the source and the colour of the image.
- Can you explain how to create a hyperlink in HTML?
There are some steps that you should follow in order to create a hyperlink in HTML.
The steps are;
The first step is to use an anchor tag <a>, then add a ‘href’ attribute. This highlights the page URL to which the link redirects. For instance, <a href=“https://www.book.com”>Visit Book</a>.
- How to differentiate between HTML tags and HTML elements?
HTML elements add opening tag, closing tag and the inside content. An example of an HTML element is <p>Hello World<Hello India</p>.
On the other hand, HTML tags are specific keywords that are applied in the form of a pair to highlight the beginning and end of an element, inserted between angle brackets. An example of HTML tags are <p> and </p>.
Elements, referred to as the whole unit containing content and tags, manage both the data and structure of a web page; on the other hand, Tags define the different types of elements and assist in highlighting their structure in the document.
- What are the different types of headings used in an HTML?
There are six types of headings an HTML tag contains. The tags are <h1> tag, <h2> tag, <h3> tag, <h4> tag, <h5> tag, and <h6> tag. Each type of heading tag offers a different text size, the largest from the lowest in ascending order. The <h1> contains the largest text size, whereas <h6> covers the smallest text size.
<h1>This is Heading h1</h1>
<h2>This is Heading h2</h2>
<h3>This is Heading h3</h3>
<h4>This is Heading h4</h4>
<h5>This is Heading h5</h5>
<h6>This is Heading h6</h6>
- Do you know how to create multi-coloured text on a web page? Explain.
Yes, I know. First, you should add the “style” attribute in HTML tags to create multi-coloured text on a web page. Use different colours to text by setting the CSS “color” accurately for every segment of text. For instance, <p style=“color:blue;”>Blue</p> <p style= “color:yellow;”>Yellow</p>.
- What do you mean by a Style Sheet?
A Style Sheet refers to a set of instructions that highlights the ways to display HTML elements. These specific elements add different styling properties, such as colour, font size, and stunning layouts. Style sheets are usually encoded as CSS or Cascading Style Sheets and are very important for developing constantly styled and visually attractive web pages.
- State the differences between XHTML and HTML.
HTML stands for Hypertext Markup Language, whereas XHTML stands for Extensive Hypertext Markup Language. The extended version of SGML is HTML, whereas XHTML is extended from HTML and XML.
In XHTML, the markup language format is used, on the other hand, the document file format is used in HTML.
Doctype is essential in XHTML to write at the top of the file; on the contrary, Doctype is not necessary in HTML.
The filename extensions are .xhtml, .xht., and .xml.
On the other hand, the filename extensions are .htm and .html.
- State the differences between HTML and HTML5.
HTML5 allows JavaScript to run in the browser, whereas there is no need for JavaScript in HTML to run in the browser.
Cookies are applied to store the temporary data in HTML, while application cache and SQL databases are usually used to store the temporary data in HTML5.
Drag-and-drop effects are enabled and supported in HTML5, while HTML does not allow drag-and-drop impacts.
In HTML, character encoding is complicated and long, while in HTML5, character encoding is very easy and simple.
HTML5 can handle inaccurate syntax, while HTML is incapable of handling erroneous syntax.

Basic CSS Interview Questions
- What do you mean by CSS?
CSS stands for Cascading Style Sheet, and this is a programming language aiming to define the presentation of a document encoded in XML or HTML. The layout, spacing, fonts, sizes and colours of elements are all highlighted by CSS. As it maintains the continuity of content and design separation, web designs can become more complex and adaptable.
- State the difference between CSS and CSS3.
The most updated version of the Cascading Style Sheets language, CSS3, provides new features not found in previous versions. Compared to the more primary style features of past CSS versions, CSS3 differs in terms of animations, rounded corners, new layout options such as Grid and Flexbox, transitions, and shadows, making complex designs very easier and more vibrant.
- State the benefits of using CSS.
There are some advantages of using CSS, and they are;
- Consistency: Dependency and user experience are boosted by continuous styles applied on all web pages.
- Ease of access: Users with impairments can get huge advantages from higher accessibility due to CSS features that change the display as well as layout.
- Effectivity: Styles help in saving file sizes and loading times as they are highlighted only once and added to different pages.
- Adaptability: Simply make adjustments in the CSS file; the look of a website can be modified quickly.
- What are the limitations of CSS?
There are some limitations of CSS, and they are as follows;
- Complexity: Since browsers vary, CSS has little authority over how web pages display in different browsers.
- Control limitation: CSS rules for advanced layouts, fonts and colours can be complex and sometimes challenging to comprehend.
- Dynamic limitations: CSS is not able to manage events, do basic processes, or execute tasks such as programming languages.
- What is the major purpose of media queries in CSS?
The major purpose of Media Queries is to enable you to use different styles and layouts depending on the distinct characteristics of devices, such as display, resolution, orientation, and screen sizes. This stunning responsiveness boosts the overall user experience by offering an optimal viewing layout over different devices, from laptops to smartphones.
- What do you mean by CSS Box Model?
The Box Model in CSS is the basic concept of web development and CSS, illustrating the way elements are developed and how space is maintained around them. It comprises the border that helps in framing and padding the content, the padding that is the space inside the border, the margin that is the space outside the border, and the content that is text or images.
- Explain the differences between margin and padding in CSS.
While both margin and padding are employed to manage specific space in web design, they have various functions in CSS. The margin of an element is referred to as the area outside its border that separates it from other components. Although, it affects the space between components rather than the original size of that element.
Negative margins have the power to fail when the margins of adjacent elements overlap. The space outside the content of a component, on the other hand, is referred to as padding. It widens the dimensions of an element and makes space beneath the component. Padding is not collapsable and cannot be incorrect, in comparison to margins.
- What is the concept of CSS pre-processors, and how are they used?
CSS pre-processors such as LESS, Sass, and Stylus are some excellent software that grows the functionalities of CSS with exclusive features such as mixins, variables, inheritance, and nesting. This helps in handling CSS with more power and ease. Such processors operate the extended syntax to develop regular CSS that browsers can easily comprehend.
- Make a list of CSS frameworks.
I have prepared a complete list of CSS frameworks, and they include;
- BootStrap
- Semantic UI
- Materialise
- Foundation
- Tailwind CSS
These functional frameworks offer ready-made elements and applicability that reduce the testing time of CSS, standardise browser support and simplify complex operations of CSS.
- Explain CSS Selectors.
CSS selectors are the aspects that highlight some elements to which some major CSS rules apply. Various types of CSS selectors are;
- Class selectors, Syntax: .class_name {
// CSS Property
}
- Attribute selectors
- Element selectors, Syntax: .element {
// CSS Property
}
- ID selectors, Syntax: #id_name {
// CSS Property
}
- Universal selector, Syntax: * { property: value; }
