标签： html css

我目前正在设计一个网站，其中包含两行，每行包含3列。由于某种原因，我的所有内容都被推到了左边。我在代码中做错了吗？

以下是我正在使用的内容

<html lang="en">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">

如果您希望容器占据页面的宽度，则需要将行包装在容器或容器流体中。

<div>
    <div class="background-box container">
            <div class="row">
                <div class="box-1 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button1"><a class="box-text" href="about-us.html">ABOUT US</button></a></h2><img src="img/info.png" class="about-img">Learn more about Mrs. Chris and Delightful Days </div>
                <div class="box-2 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button2"><a class="box-text" href="photos.html">PHOTOS</a></button></h3><img src="img/photos.png" class="photos-img">View our photo gallery</div>
                <div class="box-3 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button3"><a class="box-text" href="calendar.html">CALENDAR</a></button></h3><img src="img/calendar.png" class="cal-img">Stay up to date with our official calendar to view holidays and closed days</div>
            </div>
            <div class="row">
                <div class="box-4 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button4"><a class="box-text" href="contact-us.html">CONTACT US</a></button></h3>
                    <img src="img/phone.png" class="phone-img">Need to get in touch? View our contact page for more information </div>
                <div class="box-5 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button5"><a class="box-text" href="openings.html">OPENINGS</a></h2></button>
                    <img src="img/open.png" class="open-img">View available openings </div>
                <div class="box-6 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button6"><a class="box-text" href="pricing.html">PRICING</a></button></h3>
                    <img src="img/money.png" class="pricing-img">View our pricing page for more information</div>

使用容器流体 

<style>
/*the wrapper class*/
    .wrapper {
        margin: 0 auto;
        width: 60%;
    }
/*change the width as required*/
</style>

<div>
    <div class="background-box container-fluid">
  <div class="wrapper">
            <div class="row text-center">
                <div class="box-1 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button1"><a class="box-text" href="about-us.html">ABOUT US</a></button></h2><img src="img/info.png" class="about-img">Learn more about Mrs. Chris and Delightful Days </div>
                <div class="box-2 col-sm-4  col-md-4 col-lg-4"><h2><button class="button button2"><a class="box-text" href="photos.html">PHOTOS</a></button></h2><img src="img/photos.png" class="photos-img">View our photo gallery</div>
                <div class="box-3 col-sm-4  col-md-4 col-lg-4"><h2><button class="button button3"><a class="box-text" href="calendar.html">CALENDAR</a></button></h2><img src="img/calendar.png" class="cal-img">Stay up to date with our official calendar to view holidays and closed days</div>
            </div>
      </div>
      <div class="wrapper">
            <div class="row text-center">
                <div class="box-4 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button4"><a class="box-text" href="contact-us.html">CONTACT US</a></button></h2>
                    <img src="img/phone.png" class="phone-img">Need to get in touch? View our contact page for more information </div>
                <div class="box-5 col-sm-4 col-md-4 col-lg-4"><h2><button class="button button5"><a class="box-text" href="openings.html">OPENINGS</a></button></h2>
                    <img src="img/open.png" class="open-img">View available openings </div>

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

您可以为该元素提供保证金。
