CSS 中的符号颚化符(~)表示什么？
原文:https://www . geeksforgeeks . org/what-do-symbol-tilde-presidents-in-CSS/
在 CSS 中，符号波浪号(~)被称为后续兄弟组合符(也称为波浪号或波浪线或旋转或一般兄弟选择器)。顾名思义，它是由“颚化符”(U+007E，~)字符组成的，用于分隔两个简单选择器序列。由两个序列表示的元素在文档树中共享同一个父元素。它用于选择第一个序列之前的所有第二个序列(不一定是立即的)，或者简单地说，选择指定元素的所有兄弟元素。
语法:
first-sequence ~ second-sequence {
/* property:value; */
}
示例:
<!DOCTYPE html>
<html>
<head>
<title>CSS ~ Selector</title>
<meta charset="utf-8">
<meta name="viewport"
