What are some alternative methods to using tables for layout in PHP web development?

Using tables for layout in PHP web development is not recommended due to the lack of flexibility, accessibility issues, and difficulty in maintaining responsive design. Instead, developers should utilize CSS for layout purposes to create more efficient and visually appealing web pages.

        .container {
            display: flex;

            align-items: center;
            height: 100vh;
        }
        .content {
            width: 80%;
            max-width: 800px;
            padding: 20px;
            border: 1px solid #ccc;
            border-radius: 5px;
            background-color: #f9f9f9;
