Web Designer Interview Questions and Answers for 2025

A staple in interview questions for web designer freshers, be prepared to answer this one. There are a handful of tools available to aid web designing. These tools are used for creating websites without requiring the knowledge of HTML or CSS, editing codes, designing a website, and creating design prototypes. Some of these tools are: 

• Google Web Designer 
• Webflow 
• Adobe XD 
• Canva 
• InVision Studio 
• Adobe Dreamweaver 
• WordPress 
• Shopify 
• Wix 

When possible, it is best to utilize an external stylesheet rather than duplicating the CSS across many pages in order to control the styling of different pages at once. As opposed to inline CSS, it follows the notion of separation of concerns, which improves the readability and structure of both the CSS and the HTML. It can be used across different HTML files without the need to modify the CSS declarations each time. 

Some other benefits of using an external stylesheet: 

• They provide a centralized style of administration in which changes to one file may be applied uniformly to several. 
• It doesn't matter how often a class is used again. 
• Selectors and grouped elements make it simple to apply styles

XHTML and HTML are both markup languages, but their use cases are different. This common senior web designer interview question is answered below. 

XHTML: Extensible Hypertext Markup Language is what XHTML refers to. Since XHTML combines elements from both XML and HTML, it may be thought of as a subset of XML. When you combine XML with HTML, you get XHTML. XHTML is often seen as an enhanced form of HTML. 

HTML: Hypertext Markup Language (HTML) is the most used language on the web. Websites and their interconnectivity are made possible using HTML. Just so we're clear, HTML is a markup language and not a programming language. HTML sites may be given a fresh design with the help of additional technologies like CSS and JavaScript. 

To select a particular HTML element, the ID selector looks at its ID property. The ID selector is employed to single out a specific element on the page by its unique ID. The hash (#) character followed by an element's ID is used to select that HTML component. The ID selectors are represented as #idName. 

Example: The below-mentioned HTML component will have the ID selector- #footer. 

<div id=“footer”> It is the footer </div> 

Object-oriented representation of HTML and XML texts is done using the Document Object Model (DOM), a platform-independent programming interface. It specifies how documents are organized and how they may be retrieved. Developers are given complete control over every aspect of a document with DOM, including its layout, formatting, and content. The Document Object Model (DOM) provides a hierarchical representation of a website for the convenience of both programmers and website visitors.  

Each node in this tree represents a section of the document, and this tree is processed as if it were an object. Every branch culminates in a node, and each node has its own set of things to store. When a page is loaded into a browser, its HTML and CSS are parsed to create the Document Object Model (DOM), which is then used to render the page.

If we are building a website, utilize H1 tags as much as you want; no upper or lower limit exists. H1 tags are a fantastic method to provide hierarchy to a page, making it easier for both humans and search engines to determine which content belongs under which headings. However, as they are read by computers and web crawlers, H1 tags should be placed on web pages. Nonetheless, if you overuse H1 tags, it might hurt the website's SEO.

Any set of web designer interview questions and answers should consist of a clear idea of semantic HTML. By "semantic HTML," we mean tags that provide clear indications of their intended function to both the coder and the browser. They make an HTML page more than simply a pretty display by lending it context. The elements in semantic HTML indicate the meaning of the content being sent. HTML tags with semantic value specify their content precisely, making them accessible to both people and computers. 

The <header> and <footer> tags are some examples of semantic elements since they specify the context in which they are to be used and the data type of the material they contain. New semantic components included in HTML5 are: 

<details>, <article>, <figure>, <figcaption>, <section>, <mark>, <time>, <summary>. 

The visibility: hidden property hides the element, but it takes up space in the layout. The element will be hidden from view but not the page flow.

On the other hand, display: none eliminates the element from the document and does not take up any space. Here, the tag is removed from the normal flow of the page, which enables other elements to fill it in.

The first component of every CSS Rule is a selector. It's a sequence of nouns and verbs that specifies to the browser what HTML tags must be picked out and given the values for their stylesheet properties as defined in the rule itself. Whenever there is a need to apply a style to inline components, a CSS selector is applied in conjunction with a rule. Selectors make it simple to locate and choose HTML elements according to their name, attribute, ID, etc.

A grid system is a tool used in graphic design to help the designers with alignment and layout. This refers to a set of guidelines the designer may follow to ensure everything fits neatly into place. A grid is made up of intersecting vertical and horizontal lines, which serve to organize the page's elements. Websites can benefit from using a grid to arrange their design components in a manner that is both aesthetically pleasing and functional for site visitors. Different variations of grids serve different purposes while designing websites.

It is one of the important interview questions for web designer freshers. To answer this, a class selector in CSS consists of the period (.) followed by the class's name. It picks everything on the page that has the same class property, allowing you to apply separate CSS declarations to them individually. To put it another way, the class selector is what you use to select a certain statement so that you can tweak its HTML tag-assigned style. 

Use of class selector in CSS: 

.exampleclass {font-family: TimesNewRoman; font-size: 30; background: blue;} 
<div class="sampleclass"> 
... 
</div> 

The term "information architecture" (IA) is used to describe the methodical and long-term process of determining how to best organize, structure, and categorize data. It's a method for organizing and labeling data in a straightforward manner, making it easier for people to discover what they need. Innovation is not the only possible outcome of IA; it can also be used to reimagine an already existing design. This is the single most important factor in determining how successfully consumers will be able to navigate your website and stay engaged with its content.

The World Wide Web Consortium (W3C) is an international group that advocates for the advancement of the web. Web Standards are developed there via a collaborative process, including the public, the organization's membership, and a full-time team of specialists from across the globe. Additionally, W3C creates WWW design standards to improve communication and cooperation among the many parties involved in the web's development. W3C is there to steer the evolution of the internet toward its own potential.

In web design and other media, white space is used to visually combine and separate items, highlight a single piece, and redesign content grid or arrangement.

As well as aiding in the marketing concept and adding to aesthetic harmony, whitespace may be used to guide the eye of the user from one component to the next.

Because of this, the site is neat and organized, with content that visitors will like.

When we use HTML5 video to embed a clip on a website (instead of a video-hosting service like YouTube), the site hosting the video is responsible for delivering it in the right format that the user's browser can understand and play. Major web browsers, software platforms, and devices all presently accept the MP4 video standard incorporating MPEG4 or h.264 compressions. Backups of the clip in OGV and WebM forms are useful for the Firefox browser and certain Android devices that can't play MP4 movies.

Undefined: Whenever a variable is defined but not given a value, this situation arises. 'Undefined' is not a valid keyword. 

Example: 

var stay; 
undefined 
console.log(stay) 

Undeclared: It happens when we attempt to use a variable that hasn't been defined using the var or const keywords or hasn't been initialized. 

Example: 

//ReferenceError: myVariable is not defined 
console.log(myVariable) 

A must-know for anyone heading into a web design interview, this question is frequently asked in web design Interview Questions. The following script can help you submit a form in JavaScript after furnishing all the elements like the anchor tag and one click. 

Script: 

document.forms[0].submit()

[The value ‘0’ defines the index of the JavaScript form.]

The <this> keyword in JavaScript indicates the current object in use. The method of execution determines which entity is accessed (called or used). Depending on the usage, the <this> keyword may designate a variety of elements. But inside an object method, <this> denotes the object.

This is another important senior web designer interview question. There is a boolean element called defer. Setting this delay attribute means the script will be downloaded in parallel with page processing but will not be run until after page parsing is complete. That means its primary function is to postpone running the page's JavaScript until the parser has finished loading and initializing the page.

This is a commonly asked technical interview question for UI/UX designers. Any competent site designer must be able to weigh and comprehend these dissimilar aspects- what the designers say about the aspects they consider most important while designing. If you are designing a site for a huge financial institution, for instance, you may prioritize safety above search engine optimization (SEO). In contrast, online publications have a heightened focus on speed and SEO.

If a jQuery event handler produces a false boolean value, the event will not proceed with its corresponding function, and the handler will be removed from future execution.

The goal of CSS3, the current version of the Cascading Style Sheets language, is to expand on the capabilities of CSS2. It introduces several improvements and modifications, including the flexible box, multi-column, and grid layouts, as well as transitions, gradients, shadows, rounded corners, and animations. Previously, creative HTML hacks and applications like Photoshop were required to achieve the same level of visual flair as is now possible directly inside a web browser using CSS3.  

What makes CSS3 so special is how well it handles, reducing the need for images and code that used to be integral parts of your site's structure. This means less work for your web server and quicker page loads. One of the common topics of discussion in web design interviews is a list of the most important new features included in CSS3. Have a look- 

• Superior animation. 
• Layouts with many columns. 
• Various Gradient and Background Options. 
• Opacity. 
• Selectors. 
• Rounded corner. 

In this Agile software design method, pair programming, two designers work together on a single computer. This practice has its roots in the Extreme programming (XP) methodology. Two individuals collaborate on the design, development, and testing of user stories. This method is widely used in a fast-paced work environment. That is why pair programming is an important segment in our web designer interview questions and answers set for experienced designers.

Wrapping objects in their jQuery equivalents is done using the $() function. This is performed so that users can access all of the jQuery object's methods. We must also know that selectors may also be provided to the $() method, which will return a jQuery object containing the relevant DOM components.

The term "Content Delivery Network" (CDN) refers to a global network of servers that stores data in a centralized location for later retrieval. With a content delivery network (CDN), files may be sent at a greater speed from a server that is geographically closer to the client than your web server could be, thereby cutting down on the time it takes for the page to load. 

Because of the many benefits they provide, CDNs are commonly employed in jQuery. Here are the benefits: 

• Using a CDN significantly lessens the pressure on the hosting machine. 
• Optimizations have made jQuery frameworks more quickly accessible. 
• Significant bandwidth reductions can be achieved by using CDN. 
• To further aid with speedy page loads, CDNs may store copies of frequently visited pages in a cache.

There are two distinct types of jQuery content delivery networks (CDN): pull-style and reverse proxy. Even though the jQuery UI CDN stores a replica of the website's content, including media, requests are still sent to the web server in a conventional pull. Alternatively, a reverse proxy will take quick action upon receiving a request.

The following snippet demonstrates how to use the body background attribute to provide the image that will be used as the backdrop of a web page. 

</head>tag. 
<body background= "picture.gif"> 

The background picture can be fixed so that it remains constant while scrolling the browser. This may be done by including the 'bgproperties' element in your HTML code. 

<body background = "picture.gif"bgproperties="fixed">

Web designers can use Dreamweaver templates to separate editable and uneditable sections of a website. All web pages that make use of this template will automatically reflect the changes made on it. When using Dreamweaver templates, you can ensure that every page of your site has the same feel and design. We may make changes to all of our site's pages at once with it.

Although these tags may be used to change the appearance of the text (using EM to make it italic, STRONG to make it bold, and SMALL to make it smaller), that is not their major function, and you shouldn't use them only to make your writing seem a certain way. These tags provide a distinctive design impact not found in others (<b>). Here are the functions of these tags: 

• <em> tag: For marking up any emphasized text. 
• <strong> tag: Mostly used in headings, titles, as well as paragraphs to put stress over the word of greatest importance. 
• <small> tag: It is commonly used for side comments, disclaimers, clarifications, etc. 

Commonly the first line of code in an HTML or XHTML page is known as the DOCTYPE declaration that specifies the document type for the file. It's not a tag or component but rather a mechanism for telling browsers what edition of HTML or another markup language has been used to create the current page. Each HTML file needs a declaration of its document type to work properly. 

Example: 

< !DOCTYPE html > 
Example 
<!DOCTYPE html> 
<html>  
<body> 
    <h1>This is a Heading</h1> 
    <h2>This is HTML5 Doctype</h2> 
</body> 
</html>
