Here are some suggestions to optimize the code:
1. Use shorthand properties whenever possible. For example, instead of writing `background-size: 100% 100%;`, you can write `background-size: cover;`.
2. Consolidate similar styles into classes, instead of repeating them for every element. For example, you can create a class for the font family and apply it to all elements that use that font.
3. Remove unnecessary styles that are not being used or overwritten by other styles.
4. Use more specific selectors to target elements, instead of relying on the order of elements in the HTML. This will make the code more robust and easier to maintain.
5. Consider using a CSS preprocessor like Sass or Less, which can help you write cleaner and more organized code.
Here's an example of how the code could be optimized:

java.lang.IllegalStateException: Cannot load configuration class: com.gj.App
该异常表示无法加载配置类com.gj.App。可能的原因是该类不存在或无法访问,或者它依赖的其他类无法加载。解决此问题的方法包括:
1.检查类名是否正确,并确保它在类路径上可用。
2.检查该类是否依赖于其他类,如果是,请确保这些类也在类路径上可用。
3.检查该类是否有正确的访问权限,如果不是,请确保它们是公共的或具有正确的访问修饰符。
4.如果使用的是自定义类加载器,请确保它正确地加载了该类。
以下是一个示例代码,演示如何使用try-catch语句捕获此异常:
```java
try {
Class<?> configClass = Class.forName("com.gj.App");
} catch (ClassNotFoundException e) {
System.err.println("Cannot load configuration class: " + e.getMessage());
}
```
