Question

我正在尝试使用行和列使用引导程序在产品页面上定位产品，但由于我在页面中添加了类别栏，因此它不再起作用了。

如图所示，产品堆放在类别栏下，另一个产品位于类别栏旁边。但我希望产品能够在类别栏旁边，我不知道我做错了什么

所以基本上我想在侧边栏旁边的每一列上都有4个产品。这是我的代码：

    <?php   include_once ('templates/header.php');  ?>

css信息：

#categorymenu {
    color:black;
    background-color: #D9e5f7;
    padding:10px;
    width:250px;

}

#categorymenu ul li a {
    color:black !important;
}

#categorymenu ul li {
    list-style: none;
}

#product {
    background-color:#ccdcff!important;
    width:176px!important;
    height:230px!important;
    padding:4px;
}

Answer 1

如果你总是想在“categoriesie”的右侧有4个产品，我认为你需要在php foreach循环中将col-md-3更改为col-md-2。总需要12，所以4 + 4 * 2 = 12.此外，你永远不应该在你的CSS中使用！important。

Answer 2

检查这个html结构

#categorymenu {
    color:black;
    background-color: #D9e5f7;
    padding:10px;
    width:250px;

}

#categorymenu ul li a {
    color:black !important;
}

#categorymenu ul li {
    list-style: none;
}

#product {
    background-color:#ccdcff!important;
    width:176px!important;
    height:230px!important;
    padding:4px;
}

Answer 3

您可以尝试使用以下代码吗？我还没有测试过，但你可以尝试一下。

@ECHO off
SET workingDirectory=%~dp0
SET fileName=%1
echo using %workingDirectory% as working directory
gcc -c %fileName%.c
gcc -o %fileName% %fileName%.o -mwindows
windres -o %fileName%rc.o %fileName%rc.rc
gcc -o %fileName% %fileName%.o %fileName%rc.o -mwindows

Answer 4

您必须维护col-sm和col-md。你需要保持这些平等。在顶部，您使用col-sm-4然后col-md-3没有平等分区，我无法理解。

请参阅分区的系统 -

<div class="row">
    <div class="col-md-4">

    </div>
    <div class="col-md-8">
        <div class="row">
           <div class="col-md-3">
           ...
           </div>
           <div class="col-md-3">
           ...
           </div>
          <div class="col-md-3">
           ...
           </div>
           <div class="col-md-3">
           ...
           </div>
        </div>
    </div>
</div>

在你的情况下，可能在，
