双边框div应该合并css [英] Double borders div should merge css
问题描述
如果你看这个小提琴,你会发现边框不会合并。 >
css:
div {
float:left;
background-color:moccasin;
width:100px;
height:100px;
border:1px固体番茄;
}
div的数量是随机的,我只能给它1个类/ ID。
请记住,页面可以调整大小,并且行数可以改变。
我已经尝试了 margin-left:1px;
和last-child / n-child()选择器,但是当您调整屏幕大小或仍然会产生不必要的边框时,它们不起作用。 / p>
编辑:当我给div margin-left时,我无法移动单个像素的div: - 1px;
并给出第一个div margin-left:1px;
我会在下一行得到不需要的结果。 $ b
只需添加到div
top:-1px;
margin-left:-1px;
请检查以下示例:
div {float:left;背景色:莫卡辛;宽度:100像素;高度:100像素;边界:1px固体番茄; margin-left:-1px; margin-top:-1px;}
< div> < / DIV>< DIV>< / DIV>< DIV>< / DIV>< DIV>< / DIV>< DIV>< / DIV>< DIV>< / DIV> < DIV>< / DIV>< DIV>< / DIV>< DIV>< / DIV>< DIV>< / DIV>
CSS:
div {
float:left;
background-color:moccasin;
width:100px;
height:100px;
border-bottom:1px固体番茄;
border-right:1px固体番茄;
}
div:第一个孩子{
border-left:1px solid tomato;
}
div.first-row {
border-top:1px solid tomato;
jQuery:
var borderCollapse = function(){
var div = $('div');
var divWidth = 0;
var rows = 1;
div.each(function(){
var that = $(this);
var div = $('div');
var width = div.parent() 。宽度();
var thisWidth = $(this).width();
if(divWidth< width){
that.prev()。not(' (''border-left':'0'});
divWidth + = parseInt(thisWidth);
} else {
that.prev( ).css({'border-left':'1px solid tomato'});
divWidth = 2 * thisWidth; $ b $ rows + = 1;
}
$ b $ (行<= 1){
that.prev()。addClass('first-row');
} else {
that.prev()。removeClass('first -row');
}
});
}
borderCollapse();
$ b $(window).resize(function(){
borderCollapse();
});
If you look at this fiddle you'll see that the borders won't merge.
css:
div{
float:left;
background-color:moccasin;
width:100px;
height:100px;
border:1px solid tomato;
}
The amount of divs is random, and I can only give it 1 class/id.
Also keep in mind that the page can be resized and the amount of divs on a row can change.
I've tried margin-left:1px;
and last-child/nth-child() selectors but they don't work when you resize the screen or it still gives unwanted border.
edit: I can NOT move the divs for a single pixel, when I give the divs margin-left:-1px;
and give the first div margin-left:1px;
I'll get unwanted results in the next rows.
Just add to the div
margin-top: -1px;
margin-left: -1px;
check the following example:
div{
float:left;
background-color:moccasin;
width:100px;
height:100px;
border:1px solid tomato;
margin-left: -1px;
margin-top: -1px;
}
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
ANOTHER SOLUTION WITH JS Here is the DEMO
CSS:
div{
float:left;
background-color:moccasin;
width:100px;
height:100px;
border-bottom:1px solid tomato;
border-right:1px solid tomato;
}
div:first-child{
border-left:1px solid tomato;
}
div.first-row {
border-top: 1px solid tomato;
}
jQuery:
var borderCollapse = function() {
var div = $('div');
var divWidth = 0;
var rows = 1;
div.each(function() {
var that = $(this);
var div = $('div');
var width = div.parent().width();
var thisWidth = $(this).width();
if (divWidth < width) {
that.prev().not('div:first-child').css({'border-left':'0'});
divWidth += parseInt(thisWidth);
} else {
that.prev().css({'border-left':'1px solid tomato'});
divWidth = 2 * thisWidth;
rows += 1;
}
if (rows <= 1) {
that.prev().addClass('first-row');
} else {
that.prev().removeClass('first-row');
}
});
}
borderCollapse();
$(window).resize(function() {
borderCollapse();
});
