我是网络开发的新手。这实际上是我的第一个个人元素,我在对齐输入字段时遇到了问题。我在 XD 中设计了布局并尝试对设计进行编码。请记住,我正在处理移动布局,因此它只有大约 400 像素宽。我想我以后可以担心媒体查询的响应能力。无论如何,我已经尝试定位输入字段并使用 text-align: center; 但它不起作用。请帮忙!

这是我的页面目前的样子:

这是我需要的样子:

This is what I need them to look like]

最佳答案

input 居中如果您想使用 text-align: center父级上。您可以引入一个新元素作为父元素,也可以将其应用于 body在你的情况下。

然后是你的.defaultCalc元素不居中,因为它们是 block 元素。你可以让他们inline-block (我做了什么),或申请 margin-left: auto; margin-right: auto

你的 header元素也在 body 之前- 它需要在 <body></body>

/*Base style layouts*/

header, body {
font-family: 'Lato', sans-serif;
}

body {

border-bottom-left-radius: 46px;
border-bottom-right-radius: 46px;
background-color: #15D1BC;
box-shadow: 0px 2px 4px rgba(44,62,80,0.15);
color: #fff;
text-align: center;
}

header h3 {
margin: 0;
padding-top: 20px;
font-size: 1.25em;
font-weight: 400;
}

h4 {
font-weight: 100;
color: #95989A;
text-align: center;
}

.sections {
margin: 30px 0;
