Changing Background/Text Color of a Search Bar
提问by user1427661
I have a search bar in my navigation bar (using Bootstrap):
我的导航栏中有一个搜索栏（使用 Bootstrap）：
<li>
<form class="navbar-search pull-right">
<input type="text" class="search-query offset1" placeholder="Search">
</form>
</li>
I want to change the default background color and text color, so I've implemented the following CSS:
我想更改默认背景颜色和文本颜色，因此我实现了以下 CSS：
input .search-query {
background-color:#f47443;
color:white;
}
Yet the colors remain the same -- black and white. Is there something special about form/input background colors and font colors that I'm missing?
然而颜色保持不变——黑色和白色。我缺少的表单/输入背景颜色和字体颜色有什么特别之处吗？

You want:
你要：
input.search-query {
/* css */
}
Without the space it selects an inputelement with a class of search-query; witha space separating the terms inputand .search-querythe browser is looking inside the inputelement for a descendantelement with the search-queryclass.
如果没有空格，它会选择input一个类为search-query;的元素。用空格分隔术语input，.search-query浏览器正在input元素内部查找具有该类的后代元素search-query。
Incidentally, the selector as you wrote it:
顺便说一句，您编写的选择器：
input .search-query {
/* css */
}
could nevermatch any element, since an input(as are imgelements) void elements in that they cannot contain descendant elements or even text.
也从未与任何元素，因为一个input（因为是img元素），因为它们不能包含子元素，甚至文本无效元素。
