是否可以仅定位班级的第一级.row？

最后一个块有嵌套行：

    <div class="large-4 columns male-female-wrapper">
        {% if data.reservation.property.ymca %}
            <div class="row">
                <div class="large-4 columns selection">
                    <p>{{ 'NOOFPEOPLE'|trans }}:</p>
                </div>
                <div class="small-8 columns male-female-select">
                    <div class="row">
                        <div class="small-6 columns male-select">
                            <label>{{ 'MALE'|trans }}</label>
                            <select class="sel-box" tabindex="27" data-abide-validator="checkMaleFemale" name="numberOfMales">
                                {% for i in 0..data.numberOfGuests %}
                                    <option value="{{ i }}">{{ i }}</option>
                                {% endfor %}
                            </select>
                        </div>
                        <div class="small-6 columns female-select">
                            <label>{{ 'FEMALE'|trans }}</label>
                            <select class="sel-box" tabindex="28" data-abide-validator="checkMaleFemale" name="numberOfFemales">
                                {% for i in 0..data.numberOfGuests %}
                                    <option value="{{ i }}">{{ i }}</option>
                                {% endfor %}
                            </select>
                        </div>
                    </div>
                </div>
                <p class="tiny-text">{{ 'TOTALNUMBEROFDESC'|trans }}</p>
            </div>
        {% endif %}
    </div>

我只需要定位班级的第一级＆＃34; .row＆＃34;

我试过这个，但它不起作用：

.personal-details > .row{
    .columns:first-child{
        padding-left:0;
    }
    .columns:last-child{
        padding-right: 0;
    }
}

1 个答案:

答案 0 :(得分：3)

您的代码将编译为以下两个选择器：

.personal-details > .row .columns:first-child
.personal-details > .row .columns:last-child

您正确定位第一级.row元素，但由于嵌套的.columns元素是其自己的.row父的后代，而是第一级级别.row父级，也匹配。

所以你需要添加更多>个组合器：

.personal-details > .row{
    > .columns:first-child{
        padding-left:0;
    }
    > .columns:last-child{
        padding-right: 0;
    }
}

这将生成以下选择器，这些选择器仅匹配顶级.columns元素：

.personal-details > .row > .columns:first-child
.personal-details > .row > .columns:last-child
