I'll create an image with the requested specifications using HTML and CSS. Since we can't directly generate images in WebContainer, I'll create a template that you can use with an image editing tool or online service to add the actual Nezha background image.

To use this template:

1. Replace 'nezha-background.jpg' with your Nezha image
2. Adjust font sizes and positioning as needed
3. The text will stretch to 90% of the container width and be centered

Since we can't directly generate images in WebContainer, I'll create a pure CSS version that simulates a Nezha-themed background with the requested text. Here's the complete solution:

This creates a vibrant, animated-style background with:

1. Gradient colors resembling Nezha's red/orange color scheme
2. Decorative SVG patterns for texture
3. Responsive text that scales with viewport size
4. Strong text shadows for readability
5. Card with subtle lighting effects

Here's the HTML/CSS solution with a blue sky background and the requested text:

This creates:

1. A beautiful blue sky gradient background
2. Three floating cloud elements for visual interest
3. Large, bold white text that stretches to 90% of screen width
4. Text shadows for better readability
5. Responsive font sizes that adjust to screen width
6. Subtle animations on the clouds

Here's the HTML/CSS solution with a white cloud background and centered text:

This creates:

1. A soft white cloud background with gradient
2. Four floating cloud elements with subtle animation
3. Large, bold text centered in the middle
4. Dark gray text for better visibility on white background
5. Responsive design that works on different screen sizes
6. Subt
