Running Trends In The Website Designing!

“Trends” are often considered as advancements, new techniques, acquiring skills, and different styles in a way they appear and evolve. At LotuITHub’s website designing classes in Pune, we will leave amaze with the different styles with some fundamental web design trends from then to now! In order to learn the website designing let’s start with the existing trends to catch-up the new trends.


Illustration has flourished in the tech industry and used by different designers and artists by making pleasant designs to transfer emotions and brand values.


Typography based layouts which are the fundamental forms of designs and are used in the form of letterforms as graphic elements, for combining different styles and weights with BOLD, Italic, Serif, San-serif, and outlined.

Custom Cursors & Mouse Effects

Custom cursors are used as a novelty, often blending effects to modify the colour it changes shape, size, opacity, colour or animation in response to other elements, the organic motion is another known characteristic seen with the cursor which aspirant will learn at website designing classes in Pune.

Mixing 2d & 3d Elements

VR, AR and 3D printing are reactivating the production of 3D digital content. The parallax effect is used to fake the 3D constructed by 2D planes in different Z-axis.

UX Writing, Microcopy & Brand Personality

Microcopies, which were previously invisible, now features a voice and tone that has been designed especially for the brand to produce more human, and colloquial tone to maintain the style and coherence throughout the whole user experience.


Secondary elements and organic motion are the perfect combinations to visually enrich the site using excessive resources. The web designing course aspirant will learn the use of CSS and JavaScript for animating interfaces for control of parameters, easing curves, blending modes, filters, SVG morphing, etc, but require a lot of skill.

Responsive web design

Progressive web apps allow developers and designers to build applications similar to the web with the fullscreen and custom navigation bar, automatic updates, transitions, icon on the home screen, etc.

What are the 2020’s web designing trends?

Dark mode

At our website designing training institute you will come to know about the 2020s industry trends, the dark design is one of them, where UI design enables the dark theme option.

Immersive 3D elements

3D visuals have always delighted people, the interactive 3D design encourages users to stay longer by visually breaking down the boundaries between digital space and reality.

Soft shadows, layers and floating elements

Soft shadows and floating elements create a pseudo-3D effect and make the design more layered and more interesting. At a website design course in Pune, you will learn to use the soft shadows and floating elements to add interest and depth to give your web page a “3D Lite” look. 

Glowing, luminous colour schemes

Intriguing colour schemes will play a critical role in web design. With extreme minimalism and dark mode on the rise, glowing and luminous colours can really shine.


Website designing industry demands change with every other mode in 2020, the technical possibilities seem endless and we’re seeing designers play with extremes, reinvent previous styles and ceaselessly experiment with new techniques. Therefore, to make aspirant stand firm in this creatively changing industry LotusITHub is providing extravagant website designing guidance to the individual student.

Accessibility Issues In The Angular JS Application

Angular JS is a JavaScript-based open-source front-end web framework introduced by Google for developing single-page applications. While learning to develop single-page Angular JS Application at Angular JS classes in Pune, focused elements are the software architecture, performance, security, testability, and maintainability of the software but not the accessibility. Besides taking it for granted the Google experts are developing high-quality Angular Components and the Angular CDK (Component Development Kit), for several tools to improve accessibility.

 Angular JS training institute in Pune

How Angular and Angular CDK assist developers in solving accessibility issues?


In the Angular JS accessibility starts from the UI design phase where color palates are decided to meet the accessibility standards. With the use of right typography, simple animations and user interaction can reduce the error intensity in reading and understanding the application. The angular CDK provides a mixin CDK-high-contrast to style high contrast mode users. At the Angular JS course in Pune, users will learn a variety of assistive technologies to interact with web-based software applications.

 Accessibility attributes  

ARIA attribute is involved to provide web-accessible semantic & the attribute binding template syntax that control the values of accessibility-related attributes.


content_copy<!– Use attr. when binding to an ARIA attribute –>

<button [attr.aria-label]=”myActionLabel”>…</button>

The syntax is used for attribute bindings. Static ARIA attributes require no extra syntax.

content_copy<!– Static ARIA attributes require no extra syntax –>

<button aria-label=”Save document”>…</button>


Angular UI components

The enrolled candidate will come to know about the Angular material library at Angular JS classes in Pune The suite of reusable UI components used with the native HTML elements with the standard interaction patterns that are important to accessibility. Live Announcement is one of the most important features provided by angular CDK in the applications for the visually impaired users on various social places.


For example:

LiveAnnouncer is used to announce messages as a standard interaction pattern for screen-reader users using an aria-live region.

For example, create a component that uses an attribute selector with a native <button> element. That applies to <button> and <a>, but can be used with many other types of element.

Example: MatButton, MatTabNav, MatTable.


Using containers for native elements

The appropriate native element requires a container element. For example, the native <input> element cannot have children, so custom text entry components need to wrap an <input> with additional elements. This makes it impossible for users of the component to set arbitrary properties and attributes to the input element by creating a container component that uses content projection to include the native control in the component’s API.


Example – MatFormField


Use of Semantic HTML

With the help of native elements, the proper semantics accessibility issues can be solved to boost-up the SEO of the application. Here semantic tags like nav, aside, main, section, fieldset, header, footer, etc. come in use instead of just using div and span.

Use the correct order for headings (h1-h6).      

  • Use alt attribute on img element.
  • Use alt attribute on img element.
  • Use button’s for clickables.
  • Avoid positive tabindex .
  • Add captions for video and audio.


Accessibility for interactions
