Reaching more and more people is a priority of a webpage and that includes people with disabilities and people who use screen readers to browse the webpage. It’s our job and responsibility to provide them the same information we all receive.
Besides ensuring information, it’s crucial to use well structured, readable, maintainable code. To fill that void, HTML accessibility comes into view. It ensures us that all people get the same content and information irrespecitve of their physical condition, age, race, and location. Today, we will cover this topic in broad.
Semantic means Correct interpretation of the meaning of a word or sentence. In HTML semantic HTML men's using correct HTML to convey the right message about the document. It ensures that we used the correct HTML according to its purpose. …
Do you want a fast website? Smooth website? Then you should care about WebP. It makes websites lighter and makes it faster. WebP combines the feature of PNG and JPEG. It is the new king of the image format.
This is an image format like PNG/JPG/GIF but it has more interesting features that make it more versatile. Actually, It was developed and released by Google.
Some of its main features are:
We all are familiar with variables. But Sass Variable is magic like no other. It makes your web development fun and engaging. There are lots of ways to use Sass Variable. Let’s explore this.
Look at this code,
I used the same background-color and letter-spacing in both p and h1 tags. But in a real project, you will write the same value in many different places. If you want to change a small thing like color, then you have to go to every selector which has color property and change its value. …
Unity is strength. It also goes with Sass. In CSS import, the browser sends separate HTTP requests for each CSS file which causes poor performance. But in Sass, all the files are concatenated into one file and only one request is sent to the server which improves performance.
You want to be
Pro in Sass and CSS ?? Then, it’s mandatory to know how Sass @import works.
Let’s see What we will be learning today
Callback hell , but now with the help of Promise, writing asynchronous code became easier. Let’s dive into the topic.
It’s a Callback hell. Don’t be confused to see “hell”. if you don’t know what callback is please read this article. But Callback creates a problem which is called “Callback hell”. Callback hell makes code complicated to read and debug. So, it wasn't sustainable. …
parameter: Parameters are those values that are given at the time of function declaration. In the code below, “a” and “b” are parameters.
argument: Argument is those values that are passed to the function in the time of function invocation. In the code below “c” and “d” are arguments.
Default Parameter: It’s a value that is used when no arguments are passed to its associated parameter. …
Spread and rest operator is one of the coolest features of ECMA6. Using these operators makes our code easy to read and also they are easy to use.
Spread operator allows iterables(arrays, objects, and strings) to be expanded into single arguments. It’s denoted by three dots(…) followed by the variables or the array/string/object we want to unpack/expand. Let’s see how it works
Write the above code and run it in the console. In the first console, you will get an array as output. But in the second console, you will get only values without an array. Three dots (…) you are watching there is called spread operator. …
Destructuring: It’s a technique for unpacking objects, arrays, and assigning them to variables. What is unpacking?
Let's see how we would write code without destructuring:
By using the destructuring method, we can write the same code as
This is a very easy and understandable way of using destructuring methods. We can do the same thing with strings. This is called destructuring of…
We all love to use Keyboard Shortcuts. There is a proverb that “The more Keyboard Shorcuts you use, the more technical guy You are”. To give users the freedom to use Shortcuts there is an HTML Global Attribute Named “accesskey”. Let’s Explore it.
It is used for creating keyboard shortcuts mostly used by web designers and software designers to increase a better user experience. Also, we can focus on and target HTML elements with the “accesskey” attribute.
We can use it with “Input, area, button, legend, a label, textarea” these elements.
First, we need to create an element like this:

The scope is a term which decides which variable is accessible from which position. It decides the accessibility of variables. There are many kinds of scope.
Global scope: They are accessible from anywhere of the code
Local scope: It is mainly of two types as Function scope and blocks scope.
Function scope: Anything declared inside a function is inaccessible from the outside of the function.
Block scope: IF you declare something inside if/for/while block, it creates a block scope. Anything inside a curly brace is a block scope. But remember that only let and const can be used to create block scope. …
