优化代码
Here are some suggestions to optimize the code:
1. Combine the margin and padding styles for all elements into one declaration:
```
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
```
This will apply these styles to all elements, and reduce the amount of code needed.
2. Use shorthand properties where possible:
```
header {
position: relative;
height: 1.25rem;
background-color: transparent;
}
h1 {
font-size: .475rem;
color: #fff;
text-align: center;
line-height: 1.25rem;
}
```
By using shorthand properties, we can reduce the amount of code needed.
3. Use more descriptive class names:
```
<div class="mainbox">
<div class="column"></div>
<div class="panel"></div>
</div>
```
Using more descriptive class names can make the code easier to read and understand.
4. Use variables for repeated values:
```
:root {
--color-primary: rgba(25, 186, 139, 0.17);
}
.panel {
border: 1px solid var(--color-primary);
}
```
Using variables can make it easier to update values later on in the code.
5. Use a CSS preprocessor like Sass or Less to make the code more modular and reusable.
By using a preprocessor, we can write more efficient and maintainable code, and reduce the amount of repetition.
