如何在网格系统中添加多个元素并使其响应

Question

我是 web 开发新手，尝试在 bootstrap-4 中设计以下屏幕，但无法将其设计为响应式，有人可以描述我如何使用 bootstrap-4 网格系统设计此屏幕。

这是我正在尝试使用网格系统通过使用行和列概念来设计它的图像，它应该是响应式的。

here is my grid picture

这是我的代码：

<div className="row">
<div className="col-md-10">
    <div className="row">
        <div className="col-md-4">    
            <div className="fontStyle">
                <span className="">1</span>
                <!-- <div className="displayBlk"> -->
                <label type="text">Select Technology</label>

                    <select value=""  className="selectpicker btn btn-labeled btn-start">
                        <option value="">None Selected</option>
                        <option value="">Hello </option>
                        <option value="">World </option>
                    </select>
                <!-- </div> -->
            </div>
        </div>
        <div className="col-md-4 rowOne">
            <div className="fontStyle">
                Select Question Type                    
                <button type="button" class="btn btn-primary btn-sm">Code Type</button>
                <button type="button" class="btn btn-default btn-sm">Non Code Type</button>
            </div>
        </div>
        <div className="col-md-4">
            <div className="fontStyle">
                Number Of Questions
                <select value="" onChange="" className="selectpicker btn btn-labeled btn-start">
                    <option value="">Select</option>
                    <option value="">01</option>
                    <option value="">02</option>
                </select>
            </div>
        </div>
    </div>
    <!-- end of 10 col row -->
</div>
<div className="col-md-2">
    <span className="">
        <button type="button" class="btn btn-outline-primary btn-sm">Reset</button>
    </span>
    <span>
        <button type="button" class="btn btn-primary btn-sm">+</button>
    </span>
</div>

这是我设计后的照片。

此链接将对您有所帮助：link

网格系统最多使用 12 列，请记住这一点并相应地划分列。

但是，因为您的元素都在同一行，您应该添加 =>

class="row"

在开始使用网格系统之前。您将通过练习了解网格系统，只需使用列的值即可确定。
