【问题描述】:
我正在尝试制作如下所示的箭头
arrows
我正在使用 Sass 和 Bootstrap4,我想通过使用 css3 绘制它们来制作它们
我已经尝试过了,但我不知道如何实现它:
.line1 p{
background-color: red;
width: 80px;
height: 80px;
text-align: center;
align-items: center;
border-radius: 50%;
color: #fff;
font-size: 2rem;
}
.line1 p::before{
content:'';
display: block;
color: blue;
width: 300px;
height: 10px;
position: absolute;
border: 5px solid red;
margin: 30px 10px 0;
z-index: -1;
border-radius: 0 50px 50px 0;
background-color: red;
}
.line1 p::after{
content:'';
display: block;
color: blue;
width: 10px;
height: 200px;
position: absolute;
border: 5px solid red;
margin-left: 20px;
z-index: -1;
background-color: red;
}
<div class="col-md-3 align-items-center mr-0">
<div class="line1 my-auto">
<p class="d-block my-auto">1</p>
</div>
</div>

我来自未来,而你却做到了:
.line-container{
border-bottom: 5px solid red;
border-right: 5px dashed red;
}
.line-container::before{
content:"";
// display:block;
position: absolute;
height: 20px;
width:20px;
border-radius:50%;
background: red;
bottom:-7px;
left:0;
}
.line-container::after{
content:"2";
position:absolute;
width:55px;
height:55px;
border-radius:50%;
background: red;
bottom:-25px;
right:-7px;
font-size:2rem;
font-weight:700;
color:#fff;
text-align:center;
}
.line-container p::before{
content:"➤";
position:absolute;
font-size:32px;
color:red;
right:2.6px;
top:-30px;
transform: rotate(270deg);
}

<div class="col-8 mt-5">
<div class="line-container px-md-5 pt-5">
<p class="mt-5" >Lorem ipsum dolor sit amet, consectetur adipisicing elit. Dicta minus </p>
</div>
</div>
你只需要使用容器矩形的'线条',它们已经存在所以你只需要放置颜色
【解决方案2】:
我能够找到三角形here 的初始css。基本上,您想让 div 的两个边框透明并给它们一定的宽度,这样看起来 div 会被捏成一个三角形。除了定位之外,我还添加了非常简单的球。
您可能需要进行进一步调整以满足您的需求,但这应该可以帮助您开始 :)
.line1 p{
background-color: red;
width: 80px;
height: 80px;
text-align: center;
align-items: center;
border-radius: 50%;
color: #fff;
font-size: 2rem;
}
.line1 p::before{
content:'';
display: block;
color: blue;
width: 300px;
height: 10px;
position: absolute;
border: 5px solid red;
margin: 30px 10px 0;
z-index: -1;
border-radius: 0 50px 50px 0;
background-color: red;
}
.line1 p::after{
content:'';
display: block;
color: blue;
width: 10px;
height: 200px;
position: absolute;
border: 5px solid red;
margin-left: 20px;
z-index: -1;
background-color: red;
}
.arrow1{
position: absolute;
transform: rotate(180deg);
left: 3px;
top: 225px;
width: 0;
height: 0;
border-right: 28px solid transparent;
border-bottom: 60px solid red;
border-left: 28px solid transparent;
}
.ball1{
position: absolute;
left: 300px;
top: 15px;
background-color: red;
border-radius: 50%;
height: 50px;
width: 50px;
}
<div class="col-md-3 align-items-center mr-0" style="position: relative;">
<div class="line1 my-auto">
<p class="d-block my-auto">1</p>
<div class='arrow1'></div>
<div class='ball1'></div>
</div>
</div>

好吧,我会给你一个快速的 PoC,你可以很容易地扩展它,以便可以使用预制模板为实例定义它的使用,但如果你想要所有其他方向和东西,你将不得不做额外的创意工作并自己填写空白,但这可能有助于您入门。干杯!
