Jus*_*ten 4 html css asp.net formatting
我现在已经开始使用1.5小时了,我无法想出办法让它成为我想要的方式.我对网络上的所有东西都是新手,并且需要花费大量时间(可能更多?)来尝试将事物放在我想要的地方并以优雅的方式进行.
无论如何,我有两个文本框,上面有两个标签,并在框上方居中.我想简单地在它们之间放一个按钮,并以文本框的高度为中心.
这就像我能够达到我想要的那样接近.我希望左侧文本框移动,以便它与"跳转到:","客户:","和"客户#:"排成一行,然后右侧的框与右侧的相同距离可能是"下一步"按钮只有10px高,但仍然居中.这张照片的问题是它只在显示和展开文本框时才有效,如果它们被隐藏,那么面板实际上会在Customer#部分上方呈现,因为如何我操纵了我猜的边距.
这是我对<div>s 的尝试

这是我对表元素的尝试

所有这些<td></td><td></td><td>都试图在按钮和文本框之间放置空格,因为我无法获得浮动或边距.任何帮助将非常感激!

看起来这更像是一个CSS和HTML问题而不是ASP.Net问题.
要清楚,使用CSS在父级中垂直居中并不容易,诀窍是:
试试这个:
<style>
div.textboxArea {
text-align:center;
float:left;
width:40%;
height:400px;
}
.textboxArea textarea {
width:80%;
height:400px;
}
.centerMeVertically div {
position:absolute;
top:50%;
vertical-align:middle;
height:30px;
width:100%;
margin-top:-15px;
text-align:center;
}
div.centerMeVertically {
float:left;
width:20%;
text-align:center;
height:400px;
position:relative;
}
p {
height:35px;
margin:-35px 0 0 0;
}
.container {
margin-top:35px;
}
</style>
<div class="container">
<div style="width:100%;">
<div class="textboxArea">
<p>Label 1</p>
<textarea></textarea>
</div>
<div class="centerMeVertically">
<div><button>Button2</button></div>
</div>
<div class="textboxArea">
<p>Label 2</p>
<textarea></textarea>
</div>
</div>
</div>

编辑:看过你修改过的问题后,我修改了我的答案,只将按钮居中放在textarea的垂直位置.
你必须用顶级边缘做一些愚蠢的CSS技巧,但它完成了工作.还要注意容器div.这是为了确保如果您在标记中"放置"此代码段之上的任何内容,它就不会被标签重叠.
