在悬停时添加边框时如何防止移动? (透明边框不是解决方案) [英] How to prevent shifting when adding border on hover? (Transparent border is not a solution)
问题描述
我想在悬停时向div添加边框,但是在添加边框时div会稍微变糟。这是一个众所周知的问题,常见的解决方案是添加透明边框。 (例如, )但是,我的div中有一个带有一些文本的图片,我希望该图片的宽度为div。添加透明边框将使背景颜色显示出来,而不会占据整个宽度。
I want to add a border to div on hover, but the div shit slightly when the border is added. It is a well-known problem, and the common solution is to add a transparent border. (For example) However, I have an image with some text in my div and I want the image to take full width of the div. Adding a transparent border will makes the background color shows up and not taking the full width.
HTML:
<div class="outer-container">
<div class="inner-container" contenteditable="true">
<img src="./testing.png">
some other text
</div>
</div>
CSS:
.outer-container {
width: 100%;
background: #000000
}
.inner-container {
margin: auto;
width: 300px;
margin-bottom: 0px;
background: #FF0000;
border: 1px solid transparent;
}
.inner-container:hover {
border: 1px solid blue;
}
div的高度在实际使用中是可变的,因为它是由用户上传的。我知道我可以用javascript解决问题,但是有什么办法可以只用CSS达到预期的效果?
The height of the div is variable in actual use as it is to be uploaded by user. I know I can solve the problem with javascript, but is there a way I can make the desired effect with CSS only?
推荐答案
您只需使用 outline
属性
.inner-container:hover {
outline: 1px solid blue;
}
,如果您使用大边框
,例如: 将
设置为 outline:3px;蓝色;
然后使用 outline-offset:-3px;
and if you are using big border
eg:
set outline:3px; solid blue;
then use outline-offset:-3px;
