How to Make a Center Blur-Focused Screen on the QR Code Reading Screen?

Make a Center Blur-Focused Screen on the QR Code Reading Screen?

To create a center blur-focused screen for your QR Code scanner, you can use CSS to apply a blur filter to the entire screen except for a small centered area where the QR Code will be scanned.

Here's an example of how you can achieve this effect.

1. Create a container element for your QR Code scanner and give it a fixed position and a z-index value to make it appear on top of other content on the page.

.qr-scanner-container {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: 999;
}

2. Create a background element for the container and give it a blur filter to create the blur effect.

.qr-scanner-container::before {
  content: "";
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5); /* add a semi-transparent background color */
  filter: blur(10px); /* add a blur filter */
}

3. Create an inner element for the container to hold your QR Code scanner and center it within the container. You can add your QR Code scanner component as a child of this element.

.qr-scanner {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

4. Add any additional styling or functionality to your QR Code scanner as needed.

With these styles applied, you should see a blurred background behind your QR Code scanner that is focused on a small centered area. The size and positioning of this area can be adjusted by adjusting the dimensions and positioning of the .qr-scanner element.

Make a Focus Point in the Middle of the Background Blur on the QR Code Reading Screen?

To make a focus point in the middle of the background blur on the QR Code reading screen, you can add an image or icon to your page and position it at the center of the screen using CSS.

Here's an example of how you can achieve this effect.

1. Add an image or icon to your HTML. You can use any image or icon that you like, as long as it's visible against the blurred background.

<img src="path/to/image.png" class="focus-point">

2. Position the image or icon at the center of the screen.

.focus-point {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  z-index: 1000;
}

This CSS positions the image or icon at the center of the screen using absolute positioning and a transform rule to center it both horizontally and vertically. The z-index rule ensures that it appears above the blurred background.

3. Add any additional styling or functionality to your QR Code scanner as needed.

With these styles applied, you should see a blurred background behind your QR Code scanner with an image or icon at the center of the screen to act as a focus point. The image or icon will remain fixed in place even if the user scrolls the page or moves the QR Code scanner.
