Build A Palindrome Checker using JavaScript

If you want to create this Palindrome Checker then you need to know HTML, CSS, and javascript. Its elements are created by HTML and designed by CSS. Then, this Palindrome Checker is activated by JavaScript.

Step 1: Basic structure of Palindrome Checker

A box has been created on the webpage using the following code. Here the box’s min-width is 450px and the background color is white.

<div class=”container”>
</div>
*,
*:before,
*:after{
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}
body{

}
.container{
  width: 35%;
  min-width: 450px;
  background-color: #ffffff;
  padding: 50px 35px;
  position: absolute;
  transform: translate(-50%,-50%);

How to Check Password Strength in JavaScript

password strength checker javascript

In this article, you will learn how to create a password strength checker using JavaScript. Earlier I shared many more projects like Random Password Generator, Password Show Hide, etc. In this tutorial, you will learn how to create a javascript password strength checker.

This type of design will make your login and registration form more attractive and perfect. This type of password strength checker allows the user to input a strong and unique password.

This type of project is perfect for you if you want to add some conditions for inputting passwords in your login form.

Password Strength Checker JavaScript

In this case, the user will be able to input different types of characters to make his password even stronger. There is a progress bar to understand how strong this password is. Different colors have been added to this progress bar. These colors will indicate the quality of the password.

There are four types of steps in the bar. When you input general characters, red background color appears in 25% of the progress bar. When you input a variety of special characters into the password, the bar’s background color will increase by another 25%.

When different types of special characters, numbers, and capital letters are input into the password, then the progress bar will be hundred percent and its color will be green.

There is an icon that allows the user to see and hide the password. Hopefully, you understand this kind of strength of password check will make your login form more attractive. It was created using only HTML CSS and JavaScript.

How to Create Password Strength Checker

If you know basic HTML CSS JavaScript you can easily create a javascript password strength checker. Here I have shared a step-by-step tutorial. 

First I created a box at the top of the web page. That box contains the first input box. Then I provided an icon. That icon will help you see and hide your password. If you are a beginner then follow the step-by-step tutorial below.

Step 1: Basic structure of Strength Checker

I have created a box on the web page using the following code. Then I designed the webpage a bit using CSS and used the blue color of the background of the webpage.

<div class=”wrapper”>
  <div class=”container”>
 
  </div>
</div>
*,
*:before,
*:after{
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}
body{
  height: 100vh;
  background: rgb(38, 125, 236);
}

I designed this box using the following codes. Box width: 400px, height will depend on the amount of content. I have also used white color in the background and used a shadow all around to enhance the beauty.

.wrapper{
  background-color: #ffffff;
  width: 400px;
  padding: 40px 0;
  position: absolute;
  transform: translate(-50%,-50%);
  left: 50%;
  top: 50%;
  border-radius: 3px;
  box-shadow: 0 20px 25px rgba(0,0,0,0.2);
}
.container{
  width: 300px;
  position: relative;
  margin: auto;
}

Drag and Drop Elements Using JavaScript & CSS

Drag and Drop Elements Using JavaScript

In this tutorial, you will learn how to create javascript drag and drop elements. We see drag and drop JavaScript elements in different web pages or applications. That means we can drag those elements as we wish and keep them wherever we wish.

This type of JavaScript Drag and Drop Sortable is very easy to make. This tutorial will help you if you know basic JavaScript.

The design I have shown here is relatively advanced. Many drag elements have been used here. Earlier I shared a tutorial where I created this project by an element.

JavaScript Drag and Drop

I have created an image gallery with many images here. You can drag each of those images to the place of your choice.

If you do not understand what I am saying then watch the demo below. This preview will help you understand how it works.

As you can see I have created a small gallery of some images. Here are 6 images. Under normal circumstances, these images will stand side by side. Then you can drag and drop those images.

How to make drag and drop in javascript

Clicking on any image and dragging it will follow your mouse cursor. This type of design you can use in any of your applications or web pages. 

It will definitely give your user a new kind of experience. This javascript drag and drop is relatively easy to make.

I have given step by step tutorial below. If you only want the source code then you can see the following sections of the article. Here you will find live previews, step-by-step tutorials, and source code.

Step 1: Basic Area of Drag Elements

First created an area in which all the images can be seen in normal conditions.

<div class=”container”>
</div>

I designed the web page using the following codes. Here we have designed a background color and more on the web page.

* {
box-sizing: border-box;
margin: 0;
padding: 0;
font-family: “Recursive”, sans-serif;
}
body {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
flex-direction: column;
background-color: #333;
}

Now I will design the box in which all the images can be seen. The width of that area: 45vw, height: 40vh.

.container {
display: flex;
justify-content: center;
align-items: center;
width: 45vw;
height: 40vh;
max-width: 700px;
margin: 0 auto;
flex-wrap: wrap;
}
