这是一个CSS样式属性集合,用于设置一个文本输入框的样式,包括宽度、高度、显示方式、内边距、文字颜色和字体大小等。具体解释如下:
- width:100%:将该元素的宽度设置为其父元素的宽度,占据整个父元素的宽度。
- height:30px:将该元素的高度设置为30像素。
- display:block:将该元素设置为块级元素,即独占一行。
- padding: 0 200px:将该元素的内边距(上下各为0,左右各为200像素)。
- text-align:center:将该元素内的文本内容水平居中对齐。
- color:white:将该元素内的文本颜色设置为白色。
- font-size:16px:将该元素内的文本字体大小设置为16像素。

根据你提供的 CSS 代码,我没有看到任何明显的问题,但这些代码只是样式的一部分,也没有包括 HTML 代码,因此很难确定滚动条不工作的原因。不过,我注意到你在 `ul.head` 中设置了 `overflow: hidden;`,这可能会导致滚动条不可见或不可用。
建议你检查以下几点:
1. 确保你需要滚动条的元素上设置了 `overflow` 属性,并且值为 `auto` 或 `scroll`,例如:
```
.container {
overflow: auto;
}
```
2. 确保没有其他样式将 `overflow` 属性设置为 `hidden`,例如:
```
ul.head {
overflow: visible; /* 或者不设置 overflow 属性 */
}
```
3. 确保你的 HTML 代码正确,包含了需要滚动的内容,并且将它们包含在需要滚动的元素中。
如果你仍然无法解决问题,可以提供更多的代码和信息,以便我更好地帮助你。
