css - CSS中名词 "style"的定义是什么？

Question

名词“样式”(复数“样式”)在 CSS 上下文中的确切含义是什么？

我看过一些术语/词汇表页面，但它们似乎没有涵盖这个词:

这是一个术语定义的例子，这正是我要找的:

选择器
选择器是 CSS 行的一部分，它选择要使用属性/值对定位的元素。在下面的示例中，“#container #box”是选择器:

/* the selector is everything on the first line */
/* excluding the opening curly brace */
#container #box {
  width: 200px;
}

Answer 1

我得到的最接近答案的是“样式”指的是声明:

.a {
/*┏━━━━━ Style aka Declaration ━━━━━━┓ */
  background-color: mediumspringgreen;
}

因此“样式”指的是多个声明。

我基于口语用法:

Property: The style that you are applying to a selector, e.g. border.
Selector: The way you declare which elements the styles should apply to.

an element that has a class of “navigation” will receive the declared styles.

div[attrib^="1"] { /* styles here */ }

另一种定义似乎是指“文档样式”或“全局样式”，如 the CSS1 Spec ，虽然这并不常见:

CSS1 is a simple style sheet mechanism that allows authors and readers to attach style (e.g. fonts, colors and spacing) to HTML documents.
