防止CSS网格中出现双边框

css-grid css html

klugjo · 技术社区 · 7 年前

给定当前的CSS网格示例,如何折叠边框以避免出现双边框?

这是使用Html表实现的一件非常简单的事情。如何使用 display: grid ?

.wrapper {
  display: grid;
  grid-template-columns: 50px 50px 50px 50px;
}

.wrapper > div {
  padding: 15px;
  text-align: center;
  border: 1px solid black;
}

<div class="wrapper">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
  <div>7</div>
  <div>8</div>
</div>

不要在网格项周围使用实际的边框,而是使用容器上的背景色(表示“边框”颜色)和 grid-gap 属性(用于“边框”宽度)。

.wrapper {
  display: inline-grid;
  grid-template-columns: 50px 50px 50px 50px;
  border: 1px solid black;
  grid-gap: 1px;
  background-color: black;
}

.wrapper > div {
  background-color: white;
  padding: 15px;
  text-align: center;
}

<div class="wrapper">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
  <div>7</div>
  <div>8</div>
</div>

您可以这样做:

.wrapper {
  display: inline-grid;
  grid-template-columns: 50px 50px 50px 50px;
  border-bottom: 1px solid black;
  border-left: 1px solid black;
}

.wrapper > div {
  padding: 15px;
  text-align: center;
  border-top: 1px solid black;
  border-right: 1px solid black;
}

body {
 background:pink;
}

<div class="wrapper">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
  <div>7</div>
  <div>8</div>
</div>

另一个想法是依靠梯度来填补空白,如下所示:

.wrapper {
  display: inline-grid;
  grid-template-columns: 50px 50px 50px 50px;
  grid-gap:1px;
  background:
    linear-gradient(#000,#000) center/100% 1px no-repeat,
    repeating-linear-gradient(to right,transparent 0 50px,#000 0 51px);
  border:1px solid;
}

.wrapper > div {
  padding: 15px;
  text-align: center;
}

body {
 background:pink;
}

<div class=“包装器”>
<div>1</div>
<div>2</div>
<div>3</div>
<div>4</div>
<div>5</div>
<div>6</div>
<div>7</div>
<div>8</div>
</div>

您还可以调整初始解决方案,使其更加灵活,并且可以处理行中任意数量的项。

在整个页面上运行以下代码并调整窗口大小:

.wrapper {
  display: grid;
  max-width:800px;
  grid-template-columns: repeat(auto-fill,minmax(100px,1fr));
  border-top: 1px solid black;
  border-left: 1px solid black;
}

.wrapper > div {
  padding: 15px;
  text-align: center;
  border-bottom: 1px solid black;
  border-right: 1px solid black;
}

body {
 background:pink;
}

<div class="wrapper">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
  <div>7</div>
  <div>8</div>
  <div>9</div>
  <div>10</div>
  <div>11</div>
</div>

我通过使用 outline 所有物

.grid {
	width: 100%;
	height: 700px;
	display: grid;
	grid-template-columns: repeat(4, 25fr);
	grid-template-rows: repeat(4, 25fr);
	margin-bottom: 30px;
	grid-gap: 1px;
}

.grid-item {
	background-color: silver;
	outline: 1px solid gray; /* The outline creates the border */
	text-align: center;
	position: relative;
	z-index: 1; /* original z-index */
}

/* If you want to change the color on the hover state */
.grid-item:hover {
	outline: 1px solid red;
	z-index: 2; /* You must apply a z-index bigger than the original z-index or else some parts of the outline will be behind other grid elements */
}

<div class="grid">
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
  <div class="grid-item"></div>
</div>

.wrapper {
  display: grid;
  grid-template-columns: 50px 50px 50px 50px;
}

.wrapper > div {
  padding: 15px;
  text-align: center;
  border: 1px solid black;
  margin:0 -1px -1px 0;
}

<div class="wrapper">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
  <div>7</div>
  <div>8</div>
</div>

margin:0 -1px -1px 0;

这应该可以奏效。

有一种简单的方法可以做到这一点:

.grid {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
  grid-gap: 1px;
}

.grid__item {
  border: 1px solid gray;
  box-sizing: content-box;
  width: 100%;
  height: 100%;
}

<div class="grid">
  <div class="grid__item">1</div>
  <div class="grid__item">2</div>
  <div class="grid__item">3</div>
  <div class="grid__item">4</div>
  <div class="grid__item">5</div>
  <div class="grid__item">6</div>
  <div class="grid__item">7</div>
  <div class="grid__item">8</div>
  <div class="grid__item">9</div>
  <div class="grid__item">10</div>
  <div class="grid__item">11</div>
  <div class="grid__item">12</div>
</div>

P、这里的主要诀窍是 box-sizing: content-box . 如果不使用其他值全局覆盖它,则不需要它。但许多人使用 border-box ,在这种情况下,此替代解决了间隙问题。

我成功地使用了一个简单的方法,就是在网格项中添加一个方框阴影,以及一个列和行间距。这样,列的大小就可以始终与中确定的大小完全相同 grid-template-columns . 然后,只需更改列和行间距以及框阴影大小,即可获得更厚的边框。

.wrapper {
  display: grid;
  grid-template-columns: 50px 50px 50px 50px;
  grid-column-gap: 1px;
  grid-row-gap: 1px;
}
.wrapper > div {
  padding: 15px;
  text-align: center;
  box-shadow: 0 0 0 1px;
}

<div class="wrapper">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
  <div>7</div>
  <div>8</div>
</div>

对于那些需要处理奇数个元素和特定数量帧的人,可以使用以下方法

<style>
  .wrapper {
    width: 100%;
    display: grid;
    grid-template-columns: repeat(auto-fill, minmax(18rem, 1fr));
    border: 1px solid;
    grid-gap: 1px;
  }

  .element {
    display: flex;
    flex-direction: column;
    background-color: azure;
    min-height: 10rem;
    border: 1px solid;
    margin: -1px;
  }
</style>

<body>
  <div class="wrapper">
    <div class="element"></div>
    <div class="element"></div>
    <div class="element"></div>
    <div class="element"></div>
    <div class="element"></div>
    <div class="element"></div>
  </div>
</body>

双赢的准则是

网格项目:边框底部(&M);右边框
网格包装:边框顶部(&P);左侧边框

因此,即使顶柱不等于底柱,它也会正确

.wrapper {
  display: inline-grid;
  grid-template-columns: 50px 50px 50px 50px;
  border-top: 1px solid black;
  border-left: 1px solid black;
}

.wrapper > div {
  padding: 15px;
  text-align: center;
  border-bottom: 1px solid black;
  border-right: 1px solid black;
}

<div class="wrapper">
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
  <div>7</div>
</div>

如果您确定每行的项目数,此解决方案将适合您,

此示例适用于每行3个,但您可以编辑

.grid-container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-template-rows: 1fr;
  gap: 0;
  grid-template-areas: '. . .';
}

.grid-item {
  order: 0;
  flex: 0 1 auto;
  text-align: center;
  padding: 1rem;
  font-size: 12px;
  background-color: #e8e8e8;
  border-color: #000;
  border-style: solid;
  border-width: 0;

  border-right-width: 1px;
  border-bottom-width: 1px;
}

/*first 3 items*/
  .grid-item:nth-child(-n + 3) {
    border-top-width: 1px;
  }

/*last item on each row*/
  .grid-item:nth-child(3n + 0) {
    border-right-width: 1px;
    background-color: cadetblue;
  }
  
/*first item on each row*/

.grid-item:first-child,
  .grid-item:nth-child(3n + 1) {
    border-left-width: 1px;
    background-color: red;
  }
  
/*middel item on each row (not used)*/
  .grid-item:nth-child(3n - 1) {
   // border-left-width: 1px;
   background-color: yellow;
  }

/*last item (not used)*/
  .grid-item:last-child {
   // border-left-width: 0;
    background-color: green
    }

<div class="grid-container">

<div class="grid-item"> 1 </div>

<div class="grid-item"> 2 </div>

<div class="grid-item"> 3 </div>

<div class="grid-item"> 1 </div>

<div class="grid-item"> 2 </div>

<div class="grid-item"> 3 </div>

<div class="grid-item"> 1 </div>

<div class="grid-item"> 2 </div>


</div>
