我有这个网站
http://avocat2.dac-proiect.ro/
在那里你会找到一个按钮＆＃34;关于我们＆＃34; ...在该按钮后面是从父母继承的白色背景。
我希望背景透明。
如何删除从父级继承的样式？
这是代码HTML：
<header id="masthead" class="navbar navbar-default" role="banner">
<div class="container-fluid">
<div class="row">
<div class="col-sm-12 col-md-12 col-lg-12" style="background:transparent !important;font-size:17px;">
<img src="wp-content/themes/WordPressBootstrap-master/images/DESPRE-NOI.png" class="img-responsive img-center">
</div>
</div>
<div class="row">
<div class="col-sm-12 col-md-12 col-lg-12" style="background-color:lavender;font-size:17px;">

<div class="container">

?>
</div><!-- /.navbar-collapse -->

您可以将一个CSS类添加到About Us元素中，并将颜色覆盖为：
{background-color: transparent !important;}
或者你可以通过添加：
来内联style="background-color: transparent;"
直接在html标记上的元素，如下所示：
<div style="background-color: transparent;">Content</div>

你不能删除那样的CSS。您可以做的是将导航栏背景覆盖为透明（bootstrap为.navbar-default类提供背景颜色。）并为子项添加背景。
<header id="masthead" class="navbar navbar-default" role="banner" style="
background: transparent;

<div class="container-fluid">
