我有一个注册表格,我想在中间居中。但是,我的输入字段和按钮不完全对齐。它们的大小相同。按钮是5px宽,但我也试过这个与完全相同的宽度,问题仍然存在。有人可以向我解释为什么会这样吗?我也想知道为什么提交按钮的宽度总是更小,即使它具有相同的值?该网站可在www。http://public-journalism.com/pages/sign_up.php

答案 2 :(得分:0)
您只需要在包装器元素(width
)添加margin
和#pjsignup_container
。
代码示例
#pjsignup_container {
width: 220px;
margin: 0 auto;
padding: 10px 0px 10px 0px;
}
由于
margin: 0 auto;
/* is equal to(=) */
margin: 0 calc(50% - width/2);
示例
#eg {
width: 500px;
margin: 0 auto; /* or */ margin: 0 calc(50% - 500px/2);
}
很高兴有一天。祝你好运
