Is this code flexible enough? anyway to improve this code? `

body {
    display: flex;
    background-color: rgb(235, 201, 201);
    flex-direction: column;
    align-items: center;

this is the body of the login page of my website. It work on firefox. I am not sure how would this look like in many different browers and screen size.

These are difficult questions to answer. What do you mean by flexible enough? Flexible enough for what? Similarly, we could only know ways to improve the code if we understand what youโ€™re trying to accomplish.


Flexbox is essential for a responsive website. However, flexbox alone is not enough to make your code responsive, which means that it can adapt to different screen sizes and devices.

To make your code responsive, you need to use some other CSS techniques like:

  • Setting the viewport meta tag in your HTML head, which tells the browser how to scale and fit your web page on different screens. For example: <meta name="viewport" content="width=device-width, initial-scale=1.0">
  • Using relative units for width, height, margin, padding, font-size, etc., instead of absolute units like pixels. Relative units are based on the size of the parent element, the viewport, or the root element. For example: width: 100%; height: auto; font-size: 2rem;
  • Using media queries to apply different styles for different screen widths or heights. Media queries are rules that check the condition of the device or browser and apply the corresponding CSS styles. For example: @media (max-width: 600px) { /* styles for screens smaller than 600px */ }
  • Using responsive images that can scale up or down depending on the screen size. You can use the width and max-width properties to control the image size, or use the picture element to provide different sources for different screen sizes. For example: <picture> <source srcset="img_small.jpg" media="(max-width: 600px)"> <source srcset="img_large.jpg"> <img src="img_default.jpg" alt="Image"> </picture>

Also you can use various developer tools to see how your page would look in other devices
