我的HTML代码:

    <div id="divMainFirst">

        <div id="divInnerFirst">
            <div id="divTitleHeaderUC">
                <span id="spanTitleHeaderUC">Urgent Care Wait Time</span>
            </div>
            <div id="divSubTitleUC">
                <div id="smallText" style="padding:0 5px; position: absolute; bottom: 1%; left: 0; right: 0; color: #000000; text-align: center;">If you are experiencing a life-threatening emergency, call 911 or go to your nearest emergency room. Do not go to the urgent care center.<br>Estimated wait times are provided for general information only, may change at any time, and may not reflect your actual wait time once you arrive.</div>
            </div>
        </div>

        <div id="divInnerNext">
            <div id="divTitleHeaderFD">
                <span id="spanTitleHeaderFD">Find a Doctor</span>
            </div>
            <div id="divSubTitleFD">
                <span style="width: 100%; text-align: center;">
                    <table cellpadding="5">
                        <tr>
                            <td class="alignLeft">By Name [<a href="physicians.aspx" class="blueLinks" title="View All Physicians">View All</a>]:</td>
                        </tr>
                        <tr>
                            <td style="padding-left: 15px;">
                                <select>
                                    <option>TEST1</option>
                                    <option>TEST2</option>
                                </select>
                            </td>
                        </tr>
                        <tr>
                            <td class="alignLeft">By Specialty [<a href="medical_specialties.aspx" class="blueLinks" title="View All Specialties">View All</a>]:</td>
                        </tr>
                        <tr>
                            <td style="padding-left: 15px;">
                                <select>
                                    <option>TEST1</option>
                                    <option>TEST2</option>
                                </select>
                            </td>
                        </tr>
                        <tr>
                            <td class="alignLeft">By Location [<a href="locations.aspx" class="blueLinks" title="View All Locations">View All</a>]:</td>
                        </tr>
                        <tr>
                            <td style="padding-left: 15px;">
                                <select>
                                    <option>TEST1</option>
                                    <option>TEST2</option>
                                </select>
                            </td>
                        </tr>
                    </table>
                </span>
            </div>
        </div>
    </div>

我的CSS代码:

#divMainFirst {
    display: block;
    margin: 0 0 0 200px;
    overflow: hidden;
}
#divInnerFirst {
    display: inline-block;
    margin: 0 0 0 100px;
    height: 270px;
    padding: 0;
    width: 265px;
    vertical-align: top;
}
#divInnerNext {
    display: inline-block;
    margin: 0 0 0 50px;
    height: 270px;
    width: 265px;
    vertical-align: top;
}
#divTitleHeaderUC {
    width: 265px;
    height: 40px;
    background-color: #FFFFFF;
    text-align: center;
    box-shadow: inset 0 0 10px rgba(245, 159, 36, 0.5);
    position: relative;
}
#spanTitleHeaderUC {
    width: 100%;
    height: 40px;
    line-height: 40px;
    vertical-align: middle;
    background-color: #FFFFFF;
    font-family: 'blackjarregular';
    font-size: 18pt;
    color: #F59F24;
    font-weight: bold;
}
#divSubTitleUC {
    width: 265px;
    height: 220px;
    background-color: #FFFFFF;
    text-align: center;
    -webkit-border-radius: 0 0 5px 5px;
    -moz-border-radius: 0 0 5px 5px;
    border-radius: 0 0 5px 5px;
    -webkit-box-shadow: #F59F24 0px 2px 3px;
    -moz-box-shadow: #F59F24 0px 2px 3px;
    box-shadow: #F59F24 0px 2px 3px;
    position: relative;
}

使用上面的HTML和CSS代码,它显示以下放大并默认情况下:

enter image description here

但是当我在不同大小的屏幕上查看它时,它会改变为:

enter image description here

正如你所看到的那样,盒子的大小没有改变,也没有缩小以适应所有三个盒子,而是溢出到前两个下面的下一部分,无法看到。

如何根据放大/屏幕尺寸修改框更改?

查看@media queries中的CSS

使用media queries,您可以设置断点以更改CSS处理内容,例如在某些元素不再需要时隐藏它们所使用的设备。

查看https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries

这将为您提供更深入的查询背后的解释以及如何有效地使用它们。

使用百分比来表示一切。或@media (min-width: 768px) {}
