宽度为 100% 的输入字段“到达”进入填充

发布于 2024-10-28 06:42:32 字数 609 浏览 6 评论 0原文

我有一个带有输入字段的表格单元格。输入字段应填满表格单元格,但不会达到其填充范围。我所拥有的看起来像这样(带有 firebug):

Form Elementreaching into padding

我希望输入字段保留在蓝色内区域,而不是冲入紫色区域。

并且:当然,我首先阅读了有关此主题的所有问题。我阅读了所有内容,但找不到任何真正解决该问题的答案。

它应该适用于所有现代浏览器(ie7 也是如此);

我用 jsfiddle 制作了一个最小实时示例,其中我尝试了其他问题中的所有解决方案,但我只是无法让它发挥作用。 a) 是否有一个可行的解决方案? 和 b) 是否有一个很好且非解决方案?

为什么这在所有浏览器中都是一个问题?我认为这是 CSS 中的错误规范。因为如果我说“100%”,我当然希望元素适合“100%”的内容区域。 让它流入内边距和边距的用例是什么?

i have a Tablecell with an Inputfield in it. The Inputfield should fill up the Tablecell but not reach into its padding. What i have looks like this (with firebug):

Form Element reaching into padding

I want the inputfield to be kept inside the blue area and not raching into the purple one.

And: Of course i read all the questions here on this topic first. I read all of it and i could not find any answer which actually solved that.

It should work in all modern browsers (ie7 as well);

I made a minimal live Example with jsfiddle where i tried all the solutions in the other questions but i just could not get this to work. a) Is there a working solution for this? and b) Is there even a nice and non-workaroundish solution for this?

Why is this a problem in all browsers? I think this is a wrong specification in CSS. Because if i say "100%" of course i want the element to fit "100%" of the CONTENT Area. What is the use case for letting it flow into paddings and margins?

好吧,给你..

我使用的方法与这个答案

请参阅:http://jsfiddle.net/AKUsB/

CSS:

.inputContainer {
    background: #fff;
    padding: 3px 3px;
    border: 1px solid #a9a9a9
}
.inputContainer input {
    width: 100%;
    margin: 0; padding: 0; border: 0;
    display: block
}

HTML:

<div class="inputContainer">
    <input type="text" name="company" id="company" value="" class="formInputTextField" style="width: 100%;" />
</div>

Well, here you go..

I'm using the exact same method as this answer.

See: http://jsfiddle.net/AKUsB/

CSS:

.inputContainer {
    background: #fff;
    padding: 3px 3px;
    border: 1px solid #a9a9a9
}
.inputContainer input {
    width: 100%;
    margin: 0; padding: 0; border: 0;
    display: block
}

HTML:

<div class="inputContainer">
    <input type="text" name="company" id="company" value="" class="formInputTextField" style="width: 100%;" />
</div>

这里的问题在于盒模型,当您说 width: 100% 时,它会根据可用的像素值(您可以在 Web 检查器的“计算样式”选项下看到)应用像素值。但是,填充会添加到该宽度上,因此 5 像素的填充将计算出 100% + 10 像素的总宽度(每边 5 像素)。

要解决此问题,您需要删除填充,或将其合并到宽度值中。例如:

input { width: 100%;填充:0; }

输入 { width: 90%;填充:0 5%; } /* 宽度总计 100% */

默认情况下,大多数表单元素都会继承一定量的填充;因此,即使您没有专门对输入应用填充,它仍然在那里,因为浏览器默认它具有填充。

The problem here is with the box model, when you say width: 100% it applies a pixel value based on what's available (which you can see under the "computed styles" option of a web inspector). However, padding is then added on to that width, so a padding of 5px would compute to a total width of 100% + 10px (5 for each side).

To fix this problem, you need to remove your padding, or incorporate it into your width value. For example:

input { width: 100%; padding: 0; }

Or

input { width: 90%; padding: 0 5%; } /* width totals 100% */

Most form elements, by default, inherit some amount of padding; so even if you're not specifically applying padding to the input, it's still on there because the browser defaults it to have padding.

我认为你应该尝试使用

box-sizing: border-box

I think you should try to use

box-sizing: border-box
