Third party cookie example
Create third party cookie (
setcookie.php
):
$result = setcookie('cooname', 'V37', [
    'expires' => time() + 3600,
    'path' => '/',
    'domain' => '.sibrdzne.ge',
    'httpOnly' => true,
    'secure' => true,
    'SameSite' => 'None'
]);
Receive cookie from another domain (
getcookie.php
):
header('Access-Control-Allow-Origin:'.$_SERVER['HTTP_ORIGIN'] ?? '*');
header('Access-Control-Allow-Credentials:true');
echo $_COOKIE['cooname'] ?? 'no-cookie';
Pass cookie and fetch content from another domain (from console):
fetch('https://sibrdzne.ge/getcookie.php', {
    credentials:'include'
}).then(e=>e.text()).then(e=>console.log(e));

        $monthArray[$weekdays[$weekday]][] = $day;

git pull with and without rebase
If you prefer to rebase your local changes on top of the remote branch, you can use the rebase strategy. This essentially replays your local commits on top of the incoming remote changes. To use this strategy, you can run the following command before pulling: 
git config pull.rebase true
If you want to pull without rebase then 
git config pull.rebase false

CSS Animations
Example 1: Bouncing Ball Animation: 
<!DOCTYPE html>
<html>
<head>
  <style>
    @keyframes bounce {
      0%, 100% { transform: translateY(0); }
      50% { transform: translateY(-100px); }
    }
    .ball {
    	border-radius: 30px;
      width: 50px;
      height: 50px;
      background-color: red;
      position: relative;
      animation: bounce 2s ease-in-out infinite;
    }
  </style>
</head>
<body>
  <div class="ball"></div>
</body>
</html>
The ball moves up and down in a continuous loop. The position: relative is used to keep the ball within its container. Example 2: Sequential Animation: 
<!DOCTYPE html>
<html>
<head>
  <style>
    @keyframes slide-in {
      0% { transform: translateX(-100%); }
      100% { transform: translateX(0); }
    }
    @keyframes fade-in {
      0% { opacity: 0; }
      100% { opacity: 1; }
    }
    .card {
      width: 300px;
      height: 200px;
      background-color: #007bff;
      color: white;
      animation: slide-in 1s ease-in-out forwards, fade-in 1s ease-in-out forwards 1s;
    }
  </style>
</head>
<body>
  <div class="card">Sequential Animation</div>
</body>
</html>
This example combines two animations (slide-in and fade-in) to create a sequential animation effect on a card. The forwards keyword ensures that the final state of the animations is maintained after they finish. Example 3: Animated Typing Effect: 
<!DOCTYPE html>
<html>
<head>
  <style>
    .typing {
      font-family: monospace;
      overflow: hidden;
      white-space: nowrap;
      border-right: 3px solid;
      animation: typing 3s steps(40) infinite, blink 0.75s step-end infinite;
    }
    @keyframes typing {
      from { width: 0; }
      to { width: 100%; }
    }
    @keyframes blink {
      50% { border-color: transparent; }
    }
  </style>
</head>
<body>
  <div class="typing">Hello, I'm a typing effect.</div>
</body>
</html>
The typing animation gradually reveals the text by increasing the width of the border, and the blink animation simulates the blinking cursor. Example 4: Animated Gradient Background: 
<!DOCTYPE html>
<html>
<head>
  <style>
    body {
      margin: 0;
      height: 100vh;
      background: linear-gradient(-45deg, #007bff, #00ff00, #ff0000, #ffc107);
      background-size: 400% 400%;
      animation: gradient 10s ease infinite;
    }
    @keyframes gradient {
      0%, 100% { background-position: 0 50%; }
      25% { background-position: 100% 50%; }
      50% { background-position: 50% 100%; }
      75% { background-position: 0 50%; }
    }
  </style>
</head>
<body>
</body>
</html>
This example animates a gradient background by changing the background-position at different keyframes. The result is a visually striking and dynamic background. Example 5: Image Gallery with Hover Effect: 
<!DOCTYPE html>
<html>
<head>
  <style>
    .image-container {
      display: flex;
      flex-wrap: wrap;
      gap: 10px;
    }
    .image {
      width: 200px;
      height: 150px;
      overflow: hidden;
      position: relative;
      transition: transform 0.3s ease-in-out;
    }
    .image img {
      width: 100%;
      height: 100%;
      object-fit: cover;
    }
    .image:hover {
      transform: scale(1.1);
    }
    .caption {
      position: absolute;
      bottom: 0;
      left: 0;
      width: 100%;
      background-color: rgba(0, 0, 0, 0.5);
      color: white;
      padding: 5px;
      opacity: 0;
      transition: opacity 0.3s ease-in-out;
    }
    .image:hover .caption {
      opacity: 1;
    }
  </style>
</head>
<body>
  <div class="image-container">
    <div class="image">
      <img src="https://shorturl.at/fjsOQ" alt="Image 1">
      <div class="caption">Beautiful Landscape</div>
    </div>
    <div class="image">
      <img src="https://shorturl.at/muvW9" alt="Image 2">
      <div class="caption">City Skyline</div>
    </div>
    <div class="image">
      <img src="https://shorturl.at/bkwBE" alt="Image 3">
      <div class="caption">Sunny Beach</div>
    </div>
  </div>
</body>
</html>
This example creates an image gallery with a hover effect. When you hover over an image, it scales up and reveals a caption. The transition property is used to smoothly animate the scaling and opacity changes.
