当然可以。以下是一些不同风格的按钮美化方案：

方案1：扁平化风格按钮
```css
.btn-flat {
  display: inline-block;
  padding: 10px 20px;
  font-size: 16px;
  font-weight: bold;
  text-align: center;
  text-decoration: none;
  background-color: #007bff;
  color: #fff;
  border: 1px solid transparent;
  border-radius: 4px;
  transition: all 0.3s ease-in-out;
}

.btn-flat:hover {
  background-color: #0069d9;
  border-color: #0069d9;
}
```

方案2：透明背景按钮
```css
.btn-transparent {
  display: inline-block;
  padding: 10px 20px;
  font-size: 16px;
  font-weight: bold;
  text-align: center;
  text-decoration: none;
  background-color: transparent;
  color: #007bff;
  border: 2px solid #007bff;
  border-radius: 4px;
  transition: all 0.3s ease-in-out;
}

.btn-transparent:hover {
  background-color: #007bff;
  color: #fff;
}
```
