引導程式中的一行中的列，它們之間有空格

我在一個頁面中有重復的產品

  <div class="col-lg-12 col-md-12 col-sm-12 ">
            <div class="row">
                @foreach (var item in Model.Products)
                    {
                <div class="col-lg-3 col-md-3 col-xs-12 order-1 d-block mb-3 cart-col " style="padding-left:10px;">
                    <section>
                        <div class="cart-title text-center w-100" >
                            <a href="~/products/detail/@item.Id">  @item.Title</a>
                        </div>
                        <div class="thumb">
                            <a href="~/products/detail/@item.Id" class="d-block">

                                <img src="~/@item.ImageSrc">
                            </a>
                        </div>

                        <div class="cart-title">price: 
                            <span class="cart-title">
                                @item.Price.ToString("n0")
                            </span>
                        </div>
                    </section>
                </div>
                    }
            </div>
        </div>

它做了這樣的事情

但我想在每本書之間留出邊距，開始和結束書的位置是貨物，但每列書之間應該有空間。如果我設定

 <div class="col-lg-3 col-md-3 col-xs-12 order-1 d-block mb-3 cart-col " style="padding-left:10px;">

to

它會變成

我怎樣才能保持每一行但每列之間的空間？

這是CSS：

.cart-col {
width: 100%;
padding: 10px;
border: 1px solid #e2efef;
box-shadow: 0 0 7px 0 rgba(0, 0, 0, 0.29);
position: relative;
display: inline-block;
background: #fff;
border-radius: 10px;
margin-bottom:15px;

}

默認情況下，bootstrap col 具有左右填充。如果它沒有出現，則意味著您在 cart-col 類中定義了一些填充。所以，試試這個->

<div class="col-lg-3 col-md-3 col-xs-12">
    <div class="cart-col">

    </div>
</div>

如果您需要像 margin-buttom 這樣的空間，請將 gy-4 放在行類中。希望這會奏效。

cart-coldiv 應該在里面<div >

請將此代碼替換為

<div class="col-lg-12 col-md-12 col-sm-12 ">
    <div class="row">
        @foreach (var item in Model.Products)
        {
        <div class="col-lg-3 col-md-3 col-xs-12 order-1 d-block mb-3">
            <div class="cart-col">
                <section>
                    <div class="cart-title text-center w-100">
                        <a href="~/products/detail/@item.Id"> @item.Title</a>
                    </div>
                    <div class="thumb">
                        <a href="~/products/detail/@item.Id" class="d-block">

                            <img src="~/@item.ImageSrc">
                        </a>
                    </div>

                    <div class="cart-title">price:
                        <span class="cart-title">
                            @item.Price.ToString("n0")
                        </span>
                    </div>
            </div>
            </section>
        </div>
        }
    </div>
</div>

將justify-content-betweenBootstrap 中的類與您的flex. 所以只需將它添加為一個類，在row. 我也將更col-lg-3改為col-lg-2使四行專案不會被迫采用全寬。

.cart-col {
  width: 100%;
  padding: 10px;
  border: 1px solid #e2efef;
  box-shadow: 0 0 7px 0 rgba(0, 0, 0, 0.29);
  position: relative;
  display: inline-block;
  background: #fff;
  border-radius: 10px;
  margin-bottom: 15px;
}
