What are the common browser compatibility issues when using different positioning properties in PHP?

One common browser compatibility issue when using different positioning properties in PHP is that certain CSS properties may behave differently across browsers, leading to inconsistent layouts. To solve this issue, it is recommended to use CSS frameworks like Bootstrap or normalize.css to ensure a consistent layout across different browsers. 

<!DOCTYPE html>
<html>
<head>
    <title>Positioning Example</title>
    <style>
        .container {
            position: relative;
            width: 100%;
            height: 200px;
            background-color: lightblue;
        }
        .box {
            position: absolute;
            top: 50%;
            left: 50%;
            transform: translate(-50%, -50%);
            width: 100px;
            height: 100px;
            background-color: lightcoral;
        }
    </style>
</head>
<body>
    <div class="container">
        <div class="box"></div>
    </div>
</body>
</html>
