开发篮球游戏时出现异常，请求协助排查错误原因

Hey there, I feel your frustration—nothing's more confusing than having your game's content show up weirdly when you've put work into it. Let's go through the SCSS code you shared and break down potential issues that might be causing the display problems:

1. SVG Element (#Calque_1) Rendering Problems #

Your SVG container has these styles:

#Calque_1{
 max-width: 100vw;
 max-height: 100vh;
 overflow:visible;
}

• If the SVG itself doesn't have a properly defined viewBox attribute, it might scale incorrectly or get cut off. Double-check the SVG's internal code to ensure the viewBox matches its actual dimensions (e.g., viewBox="0 0 width height").
• The overflow:visible might let parts of the SVG spill outside the viewport unexpectedly. Try switching to overflow:hidden to contain it within the screen bounds, unless you specifically need elements to go outside.
• Since this element doesn't have a position set, it might be getting overlapped by other elements (like the .ground div). Add position:relative; z-index:1; to #Calque_1 to ensure it sits above the ground layer.

2. Z-Index and Layer Order Conflicts #

Your .ground div is absolutely positioned with z-index:0, but the SVG has no z-index assigned. If the SVG is rendering behind the ground, that would make key game elements invisible. Fix this by updating the SVG's styles:

#Calque_1{
 max-width: 100vw;
 max-height: 100vh;
 overflow:visible;
 position: relative;
 z-index: 1; // Ensures SVG is above the ground
}

3. SCSS Preprocessor Setup in CodePen #

You're using SCSS variables like $red, but if CodePen isn't set to compile SCSS to CSS, those variables will be ignored, breaking your button styles and any other uses of $red.

• Go to your CodePen's CSS settings (click the gear icon next to CSS) and make sure the preprocessor is set to SCSS, not plain CSS.

4. Font Loading Issues #

You specified font-family:'Roboto', sans-serif; but haven't included the font source. Without loading Roboto, browsers will fall back to a default system font, which might throw off your game's visual consistency. Make sure you've imported the Roboto font (e.g., via a font service) in your HTML's <head> section to ensure it displays as intended.

5. Background Image Reliability #

Your body uses a remote background image:

background: url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/3194017/bballBg.png);

• If this image fails to load, the fallback lightBlue will show, but if the image is critical to your game's layout, test if it's accessible. You can also add background-position: center; to ensure it's centered properly if it scales.

Let me know if any of these fixes resolve your issues, or if you can share more details about what exactly is displaying incorrectly (e.g., elements missing, layout shifted, styles not applying) and we can dig deeper!
