如何删除我页面右侧的空白区域？

标签： html css twitter-bootstrap

这是使用Twitter Bootstrap设计一个简单的响应式网页的任务，其中可折叠菜单按钮仅出现在超小型设备上，而且只有大型设备上的品牌名称。我认为我实现了这一目标。

但问题是在我的网页右侧，所有设备（我使用Chrome开发者工具进行测试）的这个恼人的空白区域。

任何建议删除空间，因为它使网页更紧凑，很好看。谢谢提前。我附上了一个白色空间的图像和一个链接到我的代码。

CSS代码，

/*html
{
    overflow-x: hidden;
    overflow-y: scroll;
}*/
body{
    font-family: 'Comfortaa', cursive;
}
/*Header Section*/
#brand-name{
    position: relative;
    bottom:20px;
    left: 1px;
    text-decoration:none;
}
.nav-LLC{
    border-radius: 0px;
}


}
#nav-list{
    margin-top: 10px;
}
#nav-list a {
  text-align: center;
  background-color: #e1e6ed;
  font-size: 1.1em;
  font-weight: bolder;
}
#nav-list a:hover{
    background-color: #96d4e8;
}
/*End of Header Section*/

/* Only for Extra Small Devices*/

@media (max-width: 500px){
    h1{
        font-size: 7vw;
    }
    h2{
        font-size: 7vw;
    }
}

/*Start of Body Section*/ 
h2{
    margin-top: 10px;
    margin-bottom: 20px;
    text-align: center;
    font-weight: bold;
    font-color: #0b0821;
}
.row section{

}
.row section p{
    text-align: justify;
    background-color: #e1e6ed;
}
h4{
    position: relative;
    left: 40%;*/
    font-weight: bold;
    color: #0b2730;
    /*background-color: #e1e6ed;
    margin: 0px;*/
}
/*End of Body Section*/

您需要知道的是，Web中的HTML元素有默认的CSS值，这些值在开发人员工具中隐藏了一些。  https://www.w3schools.com/cssref/css_default_values

对于您的示例，您需要添加两项内容：首先删除body的默认边距。这将删除视口边缘的白色间隙。

body {
  margin: 0;
}

由于h4，left: 40%向右拉动，以使其灵活居中，并在所有视口中查看以下代码：

h4 {
    position: relative /* remove this */;
    left: 40%; /* remove this */

    text-align: center; /* add this */
}

请记住，对于像.center-headline这样的课程来说，这是一种更好的方法，并在那里添加您需要的样式。然后你只需要复制＆amp;粘贴无后顾之忧。

在CSS中删除此行

CSS 

h4{
left:40%;/*remove this*/
}

答案 2 :(得分：0)

根据你的jsfiddle，标签下的标签（鸡肉，牛肉，寿司）。你有h4 css与位置相对和“左：40％;”。

为所有h4标签添加一个类（例如“menu-title”）。 并给出下面的CSS 

.menu-title {
  position: static;
  text-align: center;
}

尝试添加这样的Div：

<div class="container">
  <div class="col-12 col-sm-12 col-md-12 col-lg-12 col-xl-12"><!--  Add this Div-->
    <h2>Our Menu</h2>
    <div class="row">
      <section id="chicken" class="col-md-4 col-sm-6 col-xs-12">
      <h4>Chicken</h4>
      <!-- following codes -->

    </div>
  </div>
</div>

答案 4 :(得分：0)

请参阅下面的H4样式：

h4{
    position: relative;
    /* left: 40%;*/ /* this is the issue */
    font-weight: bold;
    color: #0b2730;
  text-align:center; /* if you want to center the text */
    /*background-color: #e1e6ed;
    margin: 0px;*/
}

从h4

中的CSS移除左：40％;

而是在bootstrap HTML标记中使用h4类文本中心。这是一个干净的方法。
