html - 如何在不离开区域的情况下应用内部填充

Question

<div id="divInnerFirst">
    <div id="divTitleHeaderUC">
        <span id="spanTitleHeaderUC">Urgent Care Wait Time</span>
    </div>
    <div id="divSubTitleUC">
            <div id="smallText" style="position: absolute; bottom: 0; width: 100%; 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>

样式表:

#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;
}
#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;
}
#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;
}

截图:

正如您从屏幕截图中看到的那样，文本向左和向右移动过多，难以阅读。我怎样才能应用内部填充以使文本不会向左和向右偏移太多？ 我尝试向 DIV 添加填充，但它拉伸(stretch)了 divSubTitleUC。

添加边距会产生以下效果:

Answer 1

拿走宽度，而是给它:

left:0;
right:0;

然后

padding:0 10px;

JSFiddle

left 和right“拉伸(stretch)”元素以尝试触摸父容器的两侧。由于容器是 position:relative; 它永远不会尝试突破父级的边界。
