使用CSS合并节标记的边框颜色

border css html

rahulkesharwani · 技术社区 · 7 年前

我创建了一个中心略微旋转的剖面边框。此外,我给每一面的部分不同的颜色。下面是我的基本代码:

body{
    background-color: #594451;
    color: #fff;
}

.boxed{
    position: absolute;
    margin:auto;
    /* border: 3pc solid rgba(255, 255, 255 ,1); */
    border-left: solid rgba(127, 203, 170, 1) 3pc;
    border-right: solid rgba(186, 179, 173, 1) 3pc;
    border-bottom: solid rgba(0, 171, 238, 1) 3pc;
    border-top: solid rgba(229, 99, 57, 1) 3pc;
    height: 20pc;
    width: 20pc;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -o-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    transform: rotate(45deg);
    
}

<h1>Welcome to Rahul's Lab</h1>
    <section class="boxed">
        <!-- <p>This will contain the box properly</p> -->
    </section>

我能实现彼此的边界重叠吗?是否可以只使用CSS,或者我必须为此创建单独的section/div? HTML & CSS Design and build websites

边界重叠是不可能的

但是,这里有一个只使用CSS创建效果的解决方案,使用:

倍数 linear-gradient 让我们来创建 background
background-blend-mode 混合角落里的颜色

使用背景速记语法,就像Temani在这里做的那样 https://stackoverflow.com/a/50526694/5061000

.boxed {
  position: absolute;
  margin: 5pc auto; /* Modified to better fit in tiny snippet */
  --border-pc: 10%; /* You could even use a CSS variable to store the width if you want to be able to modify it easily. Or the colors. Or both. */
  background:
    /* Shorthand syntax used below: image position/sizeX sizeY */
    linear-gradient(rgba(229, 099, 057, 1), rgba(229, 099, 057, 1)) top   /100% var(--border-pc), /* Orange with CSS var */
    linear-gradient(rgba(000, 171, 238, 1), rgba(000, 171, 238, 1)) bottom/100% var(--border-pc), /* Blue */
    linear-gradient(rgba(127, 203, 170, 1), rgba(127, 203, 170, 1)) left  /var(--border-pc) 100%, /* Green */
    linear-gradient(rgba(186, 179, 173, 1), rgba(186, 179, 173, 1)) right /var(--border-pc) 100%; /* Gray */
  background-blend-mode: multiply;
  background-repeat: no-repeat;
  height: 20pc;
  width: 20pc;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  transform: rotate(45deg);
}

<section class="boxed">
  <!-- <p>This will contain the box properly</p> -->
</section>

是的,它起作用了,但我更喜欢第一个!

.boxed {
  position: absolute;
  margin: 5pc auto; /* Modified to better fit in tiny snippet */
  --border-pc: 10%; /* You could even use a CSS variable to store the width if you want to be able to modify it easily. Or the colors. Or both. */
  /* I tried to indent it to better see the code: */
  background-image:
    linear-gradient(to top, /* Blue */
      rgba(0, 171, 238, 1) 0%,
      rgba(0, 171, 238, 1) var(--border-pc), /* example use of the CSS var */
      transparent var(--border-pc) ),
    linear-gradient(to right, /* Green */
      rgba(127, 203, 170, 1) 0%,
      rgba(127, 203, 170, 1) 10%,
      transparent 10% ),
    linear-gradient(to bottom, /* Orange */
      rgba(229, 99, 57, 1) 0%,
      rgba(229, 99, 57, 1) 10%, 
      transparent 10% ),
    linear-gradient(to left, /* Gray */
      rgba(186, 179, 173, 1) 0%,
      rgba(186, 179, 173, 1) 10%,
      transparent 10% );
  background-blend-mode: multiply; /* Added to mix the colors */
  height: 20pc;
  width: 20pc;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  transform: rotate(45deg);
}

(请注意,如果不使用 背景混合模式 你可以通过按顺序选择哪些渐变与其他渐变重叠!)

希望有帮助。

实际上不可能重叠边界,因为它们在div中总是以特定角度相交。不过,仍然可以通过制作单独的块来创建效果。财产 mix-blend-mode 允许图像提供的叠加效果。

记住 混合模式 不支持 IE/Edge .

以下是如何做到这一点:

body {
  margin: 30px
}

.block1 {
  background: rgba(127, 203, 170, 1);
}

.block2 {
  background: rgba(0, 171, 238, 1);
  transform: rotate(90deg);
  transform-origin: 20px 0;
  mix-blend-mode: color-burn;
}

.block3 {
  background: rgba(186, 179, 173, 1);
  transform: translateY(140px);
  mix-blend-mode: color-burn;
}

.block4 {
  background: rgba(229, 99, 57, 1);
  transform: translateY(30px) translateX(90px) rotate(90deg);
  mix-blend-mode: darken;
}

.block {
  height: 20px;
  width: 200px;
}

<div class="block1 block"></div>
<div class="block2 block"></div>
<div class="block3 block"></div>
<div class="block4 block"></div>

这是另一个梯度解,不需要 mix-blend-mode 。其想法是使用渐变制作每个角,以便轻松控制颜色并模拟重叠:

.box {
  margin:50px;
  height:200px;
  width:200px;
  box-sizing:border-box;
  
  background:
    /*The 4 corners*/
    linear-gradient(#905c3f,#905c3f) top left/20px 20px,
    linear-gradient(#b04d32,#b04d32) top right/20px 20px,
    linear-gradient(#02a9ae,#02a9ae) bottom left/20px 20px,
    linear-gradient(#0085aa,#0085aa) bottom right/20px 20px,
    
    /*The 4 borders*/
    linear-gradient(#e6663a,#e6663a) top/100% 20px,
    linear-gradient(#01adf0,#01adf0) bottom/100% 20px,
    linear-gradient(#7fcaac,#7fcaac) left/20px 100%,
    linear-gradient(#bab1ae,#bab1ae) right/20px 100%;  
   background-repeat:no-repeat;
   
   transform:rotate(45deg);
}

<div class="box">

</div>

我找到的唯一方法是以下方法,可能有更好的选择:

body{
    background-color: #594451;
    color: #fff;
}

.boxed1, .boxed2, .boxed3, .boxed4 {
    position: absolute;
    margin:auto;
    /* border: 3pc solid rgba(255, 255, 255 ,1); */
    box-sizing: border-box;
    height: 20pc;
    width: 20pc;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -o-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    transform: rotate(45deg);
    
}

.boxed1 {
    border-top: solid rgba(229, 99, 57, 1) 3pc;
}

.boxed2 {
    border-right: solid rgba(186, 179, 173, 1) 3pc;
}

.boxed3 {
    border-bottom: solid rgba(0, 171, 238, 1) 3pc;
}

.boxed4 {
    border-left: solid rgba(127, 203, 170, 1) 3pc;
}

<h1>Welcome to Rahul's Lab</h1>
    <section class="boxed1">
        <!-- <p>This will contain the box properly</p> -->
    </section>
    <section class="boxed2">

    </section>
    <section class="boxed3">

    </section>
    <section class="boxed4">
        <!-- <p>This will contain the box properly</p> -->
    </section>

希望这有帮助。
