是的,如果您在 CSS 中设置了 `line-height: 1.15`,它将应用于所有元素,包括 `<p>` 标签。即使您已经为 `<p>` 标签设置了自定义的 `line-height`,浏览器也会应用新的 `line-height` 值,以覆盖先前的值。这是因为 CSS 中的属性继承机制,子元素会继承父元素的属性,除非子元素已经有了自己的属性值或继承了另一个元素的属性值。如果您只想更改特定元素的 `line-height`,可以为该元素设置一个具有更高优先级的 CSS 选择器,例如使用 `id` 或更具体的类选择器。

html { line-height: 1.15; /* 1 */ -webkit-text-size-adjust: 100%; /* 2 */ }
这是 HTML 文档中的 CSS 样式,具体解释如下:
1. `line-height: 1.15;` 设置行高为当前字体大小的 1.15 倍,可以使文本更加易读和清晰。
2. `-webkit-text-size-adjust: 100%;` 在 WebKit 浏览器中,设置文本大小调整为 100%,保持默认大小,避免浏览器自动缩放文本大小。
优化代码* { margin: 0; padding: 0; box-sizing: border-box; } body { background: url(../1/backgroud.jpg) no-repeat top center; line-height: 1.15; } header { position: relative; height: 1.25rem; background-color: transparent; h1 { font-size: .475rem; color: #fff; text-align: center; line-height 1.25rem; } } //页面部分 .mainbox { display: flex; min-width: 1024px; max-width: 1920px; margin: 0 auto; padding: .125rem .125rem 0; .column { flex: 2; } .panel { position: relative; height: 4.5rem; padding: 0 .1875rem .5rem; margin-bottom: .1875rem; border: 1px solid rgba(25, 186, 139, 0.17); h2{ height: .6rem; color: #fff; line-height: .6rem; text-align: center; line-height .25rem; } } }
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.
