c# - 对齐div中的文本框和标签和按钮

Question

我正在尝试做这样的事情：

但我得到的是这样的：，

我无法理解如何在我的 html 中进行更改，我想将按钮放置在正确的位置，并且下拉菜单也与其他文本框对齐

stylesheet i wrote is like this :
<style type="text/css">
        div.label-wrapper {
            position: relative;
            min-width: 300px;
            max-width: 400px;
            height: 24px;
            display: block;
        }

            div.label-wrapper > label {
                position: absolute;
                left: 0;
                width: 100px;
                text-align: left; /* not absolutely necessary, but will be if you assign a width to the label */
                white-space: nowrap; /* Again, not totally necessary, but if you run out of space otherwise you'll get multiple lines for your label */
            }

            div.label-wrapper > input[type=text] {
                position: absolute;
                left: 115px; /* Leaves a 15px gap between end of label and start of textbox.  Increase value if you want more than 15px or decrease if you want less */
            }
            div.label-wrapper > input[type=submit] {
                position: absolute;
                left: 115px; /* Leaves a 15px gap between end of label and start of textbox.  Increase value if you want more than 15px or decrease if you want less */
            }
    </style>

和 html 是

<div>
                        <div class='label-wrapper'>
                            <asp:Label ID="Label1" runat="server" Text="Staff ID :"></asp:Label>
                            <asp:TextBox ID="staffID" runat="server" Width="150px"></asp:TextBox>
                        </div>
                        <div class='label-wrapper'>

Answer 1

我认为您必须使用float:left样式表中的选项才能完成这项工作。这是一个小示例代码：

#labelWrapper {
    float:left;
    width:480px;
    padding:10px;
    background:#9c9;
}

#textBoxWrapper{
    float:right;
    width:230px;
    padding:10px;
    background:#99c;
}

尝试将 CSS 更改为类似的内容。您不需要使用绝对定位。

    div.label-wrapper {
        min-width: 300px;
        max-width: 400px;
        height: 24px;
        float:left;
    }

        div.label-wrapper > label {
            width: 100px;
            text-align: left; /* not absolutely necessary, but will be if you assign a width to the label */
            white-space: nowrap; /* Again, not totally necessary, but if you run out of space otherwise you'll get multiple lines for your label */
        }

        div.label-wrapper > input[type=text] {
            left: 115px; /* Leaves a 15px gap between end of label and start of textbox.  Increase value if you want more than 15px or decrease if you want less */
        }
        div.label-wrapper > input[type=submit] {
            left: 115px; /* Leaves a 15px gap between end of label and start of textbox.  Increase value if you want more than 15px or decrease if you want less */
        }
