Today let's see how to create a random joke generator which will basically fetch the data from a free API. My main target is to show how to use API and put the data in HTML using javaScript.      Today we will use JokeApi website -  https://sv443.net/jokeapi/v2/  . You can read the documentation from here. We will send an fetch request to -  https://v2.jokeapi.dev/joke/Any?blacklistFlags=racist,sexist&type=single&idRange=0-319  . You can get this type of URL from JokeApi and any free API. You can replicate the same process for other APIs as well.      When we send request to this URL of the API, it will send back a response which is transformed into JSON format in JavaScript. Let's have a look on the sample JSON data -  { "error": false, "category": "Pun", "type": "single", "joke": "I bought some shoes from a drug dealer. I don't know what he laced them with, but ...

      Let's see how to generate random gradient background using JavaScript. This is very simple. We will use Math.random() of JavaScript to generate any random value we want to generate. We will have some functions in JavaScript :  1) randomElement() : To generate a random value between 0 to f or the hexadecimal digits. 2) randomColor() : To generate a random Hex color. 3) randomAngle() : To generate a random angle between 0 to 360. 4) applyBg() : To apply the background gradient to a particular element. Now , Let's see the live preview of our project. Change Background Let's understand in short how is it generating random gradient everytime. We have an inbuilt function in JavaScript called Math.rand() which generates random fraction value between 0 to 1. So if I multiply that with any number N and floor or round off the value, it will output any random value between 0 to N in integer format. This concept we have used here.  To g...

      If you are working with PHP you may have faced a problem that whenever the CSS is being updated the new styles are not shown in the PHP page. This happens due to some caching problems. In this situation you have to hard reload the CSS each time page is refreshed. Normally, you have already included the CSS like this:  <link rel="stylesheet" href="style.css" />     But to hard reload the CSS and make the styles work every time you update the CSS file, you have to include the PHP code after CSS file name with ?v=  <?php echo date('his'); ?> . So the final structure will be like:  <link rel="stylesheet" href="style.css?v=<?php echo date('his'); ?>" /> Hope, you understand the solution.

            What are URL parameters ? Let's say one URL of a site is like -   https://www.example.com/users?name=John&id=23 In this URL we can see that some parameters are passed as arguments at the end like (name=John and id=23) . This means that this particular URL is trying to do something with John of id 23. Now, let's say you are the host of this site. How can you GET these parameter values which are being opened by a user. To make it simple, suppose your website provides data for some names with ids. The data which you will show in your website depends on this parameters provided on the URL. Today, we will learn how to fetch them using JavaScript .      Let's fix a goal that whatever parameters of name and id value are in the URL we are to print them on the webpage. In this case, we will print John and 23 on the webpage. So, let's begin.          In JavaScript, window.location returns the ...

  CDN stands for Content Delivery Network for websites. In an easy manner, CDN is a place from where your website files (css, js, images) are loaded, as a result the load on your hosting server decreases and the CDN services are spread around the whole world to serve the files faster. Also your website may have image files which you also can upload to the CDN and serve to your website directly. Your website hosting will only have the HTML files or any dynamic contents. In that case your website speed will noticeably increase. So, now let's learn how can we make our own CDN completely free of cost.  STEP 1: Sign In to GitHub:      GitHub is an open source platform for developers for storing, managing, sharing and updating their codes or programs. So, you have to sign in to GitHub. If you don't have an account in Github, make sure to create one Follow Here .

     In any modern responsive website you have surely seen an toggle sidebar which will open and close with an animation whenever the hamburger icon or menu icon is clicked. It looks nice with nice transition and is necessary to make your website responsive for mobiles.      Today, I will let you make your own toggle sidebar which you can implement in any website and give your website a modern enhancement. We will have to do three things,  1. Making the HTML of the menu button and sidebar 2. Adding CSS to the elements 3. Using JavaScript, enabling the toggle functionality. HTML:      One thing to be noted that the HTML code of the Menu and Sidebar can be given anywhere inside the body tag because we will finally give these elements fixed positions. Better put it just after the body.  <div id="mobile-navigation"> <ul> <li><a href="#">Home</a></li> <li>...

            Yes, Nature loves symmetry. Though man discovered mathematics to solve real life and abstract problems, the Nature also obeys some mathematical rules. And sometimes, we all come to a very strange understanding seeing the unsolved mysteries of mathematics. One of that mysteries is the Collatz Conjecture or the 3n+1 conjecture .      This is nothing but a very simple procedure which we can apply to any number. But the fact all the numbers tested on this procedure come to the same output result. Let's say, we have a number N .  If it is odd then multiply it by 3 and add 1, meaning 3N+1 . And if it's even then divide it by two or calculate N/2 . And follow this steps again and again.     let's take any number 19. Odd number so 3*19+1 = 58. It is even so calculate 58/2 = 29. Now odd 3*29+1 = 88 and so on... 88 /2 =  44                   44 /2 =  22 22 /2 =...
