css怎么写突出的圆,圆形突出显⽰

圆形突出显⽰css3(Circular highlight css3)
如何在⽹站上的任何对象上制作圆形突出显⽰....
我⼀直在四处寻,⼏乎不到任何相关的⽂档。 虽然我似乎相信现在⽤css可以做任何事情,但有些东西告诉我这只能⽤像canvas这样的东西来获取并占⽤⼤量内存。
我见过的唯⼀⼀篇关于这个的帖⼦就是这个... (jquery)遮屏整个屏幕并突出显⽰页⾯的⼀部分? 虽然他们没有解决那⾥的通告问题
我已经在⼀些⽹站上看到如何突出显⽰某个元素,但是如何将突出显⽰的区域设为圆圈呢? 通过仅添加z-index使正⽅形元素显⽰在叠加层上⽅,似乎不可能使该区域成为圆形。
也许我可以对包含在圆圈中的每个元素进⾏z索引,并在边缘周围创建与叠加相同颜⾊的阴影(但如果聚光灯需要运⾏到背景的⼀部分上,我需要包括整个背景和这可能会变得丑陋)......在某些情况下,这实际上可能有效,但听起来有点怪,不是吗?
任何⼈都有⼀个很好的解决⽅案,突出显⽰页⾯上的对象,但突出显⽰为⼀个圆/⼏乎像聚焦⼀个元素...
how to make a circular highlight over any object on
I been looking around and can't find almost any documentation for this. Although I seem to believe that anything is possible now with css, something tells me this would only be available with something like canvas and take a lot of memory.
The only other post I've seen about this is (jquery) Blackout the entire screen and highlight a section of the page? although they didnt address the circular issue there
I've seen on a few sites how to highlight a certain element, but how exactly would you make the highlighted area a circle? By only adding z-index to make a square element show above the overlay, it seems impossible to make the area a circle..
Maybe I could z-index every element that would be included in the circle and create a shadow around the edges the same color as the overlay(but if the spotlight needs to run onto part of the background i would need to include the entire background and that could turn ugly)...this may work actually, in certain cases, but that sounds a bit jenky, no?
anyone have a good solution for highlighting objects on a page but that highlight being a circle / almost like spotlighting

你可以⽤border-radius和box-shadow做到这⼀点⾄少这是我⽤纯 css想到的唯⼀⽅法
你做的是制作⼀个带有transparent背景的圆形元素,然后你给它⼀个完全⿊⾊的box-shadow ,它将填满整个页⾯,你可以得到⼀些惊⼈的效果。
⽰例代码
#torch{
width: 200px;
height: 200px;
background: transparent;
border-radius: 50%;
position: fixed;
box-shadow: 0px 0px 0px 2000px #000, 0px 0px 50px inset;
}
不要忘记添加前缀-moz-, -webkit- ..etc如果需要,不要忘记你的z-index 。
You can do this with border-radius and box-shadow at least that's the only way I can think of with pure css
What you do is you make an element that is circle with a transparent background, then you give it a box-shadow completely black that will fill the whole of your page, and you can get some amazing effects.
Example code
#torch{
css怎么创建
width: 200px;
height: 200px;
background: transparent;
border-radius: 50%;
position: fixed;
box-shadow: 0px 0px 0px 2000px #000, 0px 0px 50px inset;
}
Don't forget to add your prefixes -moz-, -webkit- ..etc and don't forget your z-index if you need it.

div的宽度和⾼度应该相同以产⽣⼀个圆。 例如: http : //jsfiddle/wGzMd/ 这是CSS: div{
position: absolute;
top: 50px;
left: 50px;
width:100px;
height:100px;
border: 1px solid green;
background: green;
border-radius: 360px;

这个选择器: #awesome .favorite:not(#awesome) .highlight
⽐这个具有更⾼的特异性: #awesome .highlight:nth-of-type(1):nth-last-of-type(1)
关于我的头顶,我不知道nth-of-type或⾮声明是如何影响特异性的,但粗略地说,第⼀类有两类,第⼆类只有⼀类,所以它有点意义,它会是更具体。 在CSS中,更具体的选择器会覆盖不太具体的选择器,⽽不管顺序如何,所以您的⽂本是红⾊的。 当然,如果你拿出红⾊课,

在CSS中轻松完成的是旋转某些东西。 为了使它以椭圆形状环绕,你可以使旋转的地⽅变形。 并且,要使正在旋转的对象保持纵横⽐,您需要撤消先前的变换。 HTML:

width: 80%; /* normal case */
}
/* special case if screen width < 500 */ @media all and (max-width: 500px) { .mydiv {
