WordPress contact form 7 合并列问题

我正在尝试使用col-sm-4类将3个字段分组为一行, 但是我对行的显示方式有疑问。如下图所示, 它显示为偏离中心且不在列内。

我的表单的代码如下：

<div class="hb-comment__form">
<h3 class="h3-header">Make a Booking</h3>
<div class="row">
    [response]
    <div class="col-sm-12">
        [text* your-name class:input__field class:size-2 placeholder "Your Name"]
    </div>
    <div class="col-sm-12">
        [email* your-email class:input__field class:type-2 class:size-2
        placeholder "Your Email"]
    </div>
    <div class="col-sm-12">
        [tel* telephone_number class:input__field class:type-2 class:size-2
        placeholder "Your Phone Number"]
    </div>

        <div class="row">
            <div class="contactFormPickers">
                <div class="row">
                    <div class="col-sm-5">
                        <label>
                            Arrival Date :[date* Arrival_Date class:input__field class:type-2
                            class:size-2]
                        </label>
                    </div>
                    <div class="col-sm-5">
                        <label>
                            Depart Date: [date* Depart_Date class:input__field class:type-2
                            class:size-2]
                        </label>
                    </div>
                    <div class="col-sm-2">
                        <label >
                            Guests: <br />
                            [select* no_of_guests class:input__field class:type-2 class:size-2 class:guest-picker include_blank "2" "3" "4" "5" "6" "7" "8" "9" "10"]
                        </label>
                    </div>
                </div>
            </div>
        </div>
</div>
[textarea* your-message class:input__field class:type-2 class:size-2
placeholder x5 "Your Message"] [recaptcha] [submit class:btn class:mb-0
class:btn--normal class:btn--md "Submit Booking"]

定制的CSS类” contactFormPickers”如下所示：

.contactFormPickers{
text-align:center;
margin: auto 0;

}

解决上述问题的任何帮助将不胜感激

因此, 这显然是一个引导问题。你将这三个元素两次包装到.row元素中(这增加了某些边距和填充设置)-你应该至少擦除这些.row层之一。

另外, 如果你真的不需要.contactFormPickers层, 则可以考虑将其删除。
