너비가있는 CSS 입력 : 100 %가 부모의 경계를 벗어납니다.
로그인 양식을 삽입 패딩이있는 두 개의 입력 필드로 구성하려고하지만이 두 필드는 항상 부모의 경계를 초과합니다. 이 문제는 추가 된 삽입 패딩 에서 비롯됩니다 . 이 문제를 해결하기 위해 무엇을 할 수 있습니까?

주의 : 코드가 가장 깨끗하지 않을 수 있습니다. 예를 들어, 텍스트 입력을 캡슐화하는 span 요소는 전혀 필요하지 않을 수 있습니다.

다른 답변은 너비를 하드 코딩하거나 브라우저 특정 해킹을 사용한다고 말합니다. 더 간단한 방법이 있다고 생각합니다.
By calculating the width and subtracting the padding (which causes the field overlap). The 20px comes from 10px for left padding and 10px for right padding.
input[type=text],
input[type=password] {
...
width: calc(100% - 20px);
}
Padding is added to the overall width. Because your container has a pixel width, you are better off giving the inputs a pixel width too, but remember to remove the padding and border from the width you set to avoid the same issue.
Try changing the box-sizing to border-box. The padding is adding to width of your input elements.
CSS
input[type=text],
input[type=password] {
width: 100%;
margin-top: 5px;
height: 25px;
...
}
input {
box-sizing: border-box;
}
I tried these solutions but never got a conclusive result. In the end I used proper semantic markup with a fieldset. It saved having to add any width calculations and any box-sizing.
It also allows you to set the form width as you require and the inputs remain within the padding you need for your edges.
In this example I have put a border on the form and fieldset and an opaque background on the legend and fieldset so you can see how they overlap and sit with each other.
<html>
<head>
<style>
form {
width: 300px;
margin: 0 auto;
border: 1px solid;
}
fieldset {
border: 0;
margin: 0;
padding: 0 20px 10px;
border: 1px solid blue;
background: rgba(0,0,0,.2);
}
legend {
background: rgba(0,0,0,.2);
width: 100%;
margin: 0 -20px;
padding: 2px 20px;
color: $col1;
border: 0;
}
input[type="email"],
input[type="password"],
button {
width: 100%;
margin: 0 0 10px;
padding: 0 10px;
}
input[type="email"],
input[type="password"] {
line-height: 22px;
font-size: 16px;
}
button {
line-height: 26px;
font-size: 20px;
}
</style>
</head>
<body>
<form>
<fieldset>
<legend>Log in</legend>
<p>You may need some content here, a message?</p>
<input type="email" id="email" name="email" placeholder="Email" value=""/>
<input type="password" id="password" name="password" placeholder="password" value=""/>
<button type="submit">Login</button>
</fieldset>
</form>
</body>
</html>
Padding is essentially added to the width, therefore when you say width:100% and padding: 5px 10px you're actually adding 20px to the 100% width.
Do you want the input fields to be centered? A trick to center elements: specify the width of the element and set the margin to auto, eg:
margin : 0px auto;
width:300px
A link to your updated fiddle:
You also have an error in your css with the exclamation point in this line:
background:rgb(242, 242, 242);!important;
remove the semi-colon before it. However, !important should be used rarely and can largely be avoided.
