### Issue: Dash (`-`) causing W3C validator error and CSS issues
**Problem**:
The use of a dash (`-`) in certain areas is triggering errors in the W3C validator and affecting the proper functioning of CSS.
1. **HTML Issue**: The dash might be incorrectly placed in attribute names or element IDs, causing validation errors.
- Example: `data-name` is fine, but ensure it's used correctly and within the valid context.
2. **CSS Issue**: If the dash is used improperly in class or ID names, it can cause selector issues in CSS.
- Example: `.my-class-name` is correct, but make sure that the class is correctly applied to the element and styled properly in CSS.
**Proposed Fix**:
- Ensure that any attribute or class names are formatted correctly. For example, `data-name` is valid, but check for any spelling mistakes or misplaced dashes.
- In CSS, ensure proper selector syntax like:
```css
.my-class-name {
/* Styles here */
}
