The best way to create a dynamic dark mode in JS for your website

Dark Mode

Dark Mode seems to be here to stay. Initially, manly used by developers in their code editors, but now it’s all over the place, from mobile, desktops, and now even the web. Supporting Dark Mode is more and more turning from a nice to have, to a must-have. Of course, depending on your niche, but if you are here, chances are, you want to implement Dark Mode on your site or for your clients.
When it comes to dark mode for websites there are multiple approaches on the web.

Using JS and CSS

The first work is by the use of “dark” magic :p, joke aside, it’s very simple and elegant, and consists of really one line of CSS. 
html {
  
}

html[data-theme='dark'] {
    background: #000;
    filter: invert(1) hue-rotate(180deg)
}
What? You are probably wondering how that could work, and you may be right to be skeptical, but it does indeed. Let’s see it in action before we talk about why I don’t like this option so much:
This is the html script 
<html>
  <body>
  <h1>Hello World</h1>
    <h2>Welcome to my Dark Mode Test</h2>
    <p>
      Here is some text to convert to dark mode
   
   </p>
    
    <img alt="test" src="https://trednix.com/featured.png" width="100px" />
    
   <br />
    
  <button onclick="toggleTheme('dark');">Dark</button>
    
  <button onclick="toggleTheme('light');">Light Mode</button>
  </body>
The CSS script has been given above.
Now let's give the js scripts:
const htmlEl = document.getElementsByTagName('html')[0];

const toggleTheme = (theme) => {
    htmlEl.dataset.theme = theme;
}
Now everything works smoothly and really nice but if you reload the page,it would return to its initial ,which was the light mode , we want it to be dynamic and to do so,js got us covered.we also want to make sure our changes are stored on the browser so that we remember the user preference for the next time he/she visits our site. For that we will use the localStorage API. 
// Capture the current theme from local storage and adjust the page to use the current theme.
const htmlEl = document.getElementsByTagName('html')[0];
const currentTheme = localStorage.getItem('theme') ? localStorage.getItem('theme') : null;

if (currentTheme) {
    htmlEl.dataset.theme = currentTheme;
}

// When the user changes the theme, we need to save the new value on local storage
const toggleTheme = (theme) => {
    htmlEl.dataset.theme = theme;
    localStorage.setItem('theme', theme);
}

Email OTP

In this method, a one-time password is generated dynamically and sent to the user who attempts login. OTP can be sent to the user’s email or his mobile phone.

You can check our mobile sms otp too!  In this example, when the registered user enters email to login, an OTP code is sent to the email address. Using this OTP code the user will be validated.

How to block user IP address from your website in PHP

how to block your website user using their ip address blocking users from your site There are many reasons you may need to block an IP address from visiting your website. For example, to prevent particular users doing malicious things with your website - trying to spam your web forms, or hack your shopping cart, etc. Using PHP, you can easily find your site visitors' website addresses and based on these addresses to redirect them to specific places on your site. If you use such IP ban protection on your website, you will also need to not only list individual addresses to be blocked but also IP masks and IP ranges. In this tutorial I would show you how you can do that.But,it would be manual .i'd talk about manual and automatic way to do it. Let's start! First, we will create an array to list all the IP addresses that we want to block. Besides single IP addresses, we will also use IP ranges such as 216.58.197.101-216.58.197.200 and IP masks 100.88.*.*. Here is the arr...
