Question

我是网络开发的新手。在这里，我正在尝试开发，

这是一个模态主体。所以，我所做的是

<div className="row modalRowMargin textStyle" >
              <div className="col-1 col-md-1 border border-primary text-vertical-center" >
                <h5 className="textStyleOfQuestionLabel">Q{props.questionNo} </h5>
              </div >

              <div className="col-11 col-md-11 border" >
                < textarea className="form-control textarea border-0" style={{ resize: 'none' }} onChange={(e) => { props.onChangeQuestion(e, "question") }} > </textarea>
              </div >
            </div>

            <div className="row modalRowMargin rowTopMargin" >
              <div >
                <span >
                  Answer Choice </span> </div > </div>

            <div className="row modalRowMargin rowTopMargin " >
              <div className="col-6 col-md-6" >

                <div className="row " >

                  <div className="col-2  border border-primary text-vertical-center"
                    style={{ borderColor: props.setDefaultColor(0), color: props.setDefaultColor(0) }} >

我的CSS

saveButtonStyle{
background-color: #20B2AA;
color: white;
margin:0 auto;
    display:block;
}

.text-vertical-center{
    display:flex;
    align-items:center ;
    justify-content: center;
}

.textStyleOfLabel{
    font-size:22px;
    font-weight:bold;
}

.textStyleOfQuestionLabel{
    font-size:26px;
    font-weight:bold;
}

.checkboxStyle{
    display:flex;
    justify-content: center;
}
.containerOfcustomCheckbox {
    display: block;
    position: relative;
    padding-left: 35px;
    margin-bottom: 12px;
    cursor: pointer;
    font-size: 22px;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
    margin-left: 16px;
}

/* Hide the browser's default checkbox */
.containerOfcustomCheckbox input {
    position: absolute;
    opacity: 0;
    cursor: pointer;
    height: 0;
    width: 0;
}

/* Create a custom checkbox */
.checkmark {
    position: absolute;
    top: 0;
    left: 0;
    height: 25px;
    width: 25px;
    background-color: #eee;
    outline: 2px solid #20B2AA;
}

/* On mouse-over, add a grey background color */
.containerOfcustomCheckbox:hover input ~ .checkmark {
    background-color: #ccc;
}

/* When the checkbox is checked, add a new background */
.containerOfcustomCheckbox input:checked ~ .checkmark {
    background-color: #20B2AA;
}

/* Create the checkmark/indicator (hidden when not checked) */
.checkmark:after {
    content: "";
    position: absolute;
    display: none;
}

/* Show the checkmark when checked */
.containerOfcustomCheckbox input:checked ~ .checkmark:after {
    display: block;
}

/* Style the checkmark/indicator */
.containerOfcustomCheckbox .checkmark:after {
    left: 9px;
    top: 5px;
    width: 5px;
    height: 10px;
    border: solid white;
    border-width: 0 3px 3px 0;
    -webkit-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    transform: rotate(45deg);
}
.questionInput{
    text-align: center;
}
.textarea {
    display:inline-block;
    vertical-align:middle;
}
.modalfetchedInfoStyle{
    background-color: white;
}

所以我在这里使用引导网格系统来完成此操作。

但是我实际上遇到了平板电脑视图的问题。我只想知道如何使用html css和bootstrap实现这种结构。

这是我尝试过的。

有人可以帮我吗？

任何建议都会很有帮助

谢谢。

根据您共享的代码，meta标签具有属性shrink-to-fit=no导致您的视口无法在不同的设备宽度上进行调整。只需从meta标签中删除shrink-to-fit=no，它就可以解决此问题。有关详细说明，请查看此link。
