How to create a full width triangle at the bottom? - html

Question

I want just to do that:
However I have a lot of troubles to do it with css... Someone can help me?
This is my better try:
.flag.vertical {
background-color: #dd7758;
height: 0;
padding-bottom: 25px;
text-align: center;
color: white;
border-style: solid;
border-width: 0 10px 10px 10px;
border-color: transparent transparent white transparent;
}
<div class="flag-wrapper"><span class="flag vertical">-5%</span></div>
My doubts are about to make this white triangle on the bottom. Doesn't matter here the vertical align of the text and the font family.

Answer 1

Set the width to 0
.flag-wrapper{ background-color: #dd7758;
height: 0;
padding-bottom: 25px;
text-align: center;
color: white;
border-style: solid;
border-width: 20px 20px 20px 20px;
border-color: transparent transparent white transparent;
width: 0;
}
span{
margin-left:-10px
}
<div class="flag-wrapper"><span>-5%</span></div>

You can user after element for a triangle
Edit: You can use clip-path to make a shape as you want
This also solves your Another question that maybe do you know. If I want to add this div over an image, is it possible that the triangle will be transparent instead of white? comment
.flag.vertical {
background-color: #dd7758;
padding: 10px 10px 25px;
text-align: center;
color: white;
display: inline-block;
clip-path: polygon(0% 0%, 100% 0%, 100% 100%, 50% 70%, 0% 100%);
}
<div class="flag-wrapper"><span class="flag vertical">-5%</span></div>

Here is an idea with gradient where it will be responsive and you will have better support than clip path:
.flag-wrapper {
background-color: #dd7758;
padding:10px 5px 30px;
margin:10px;
text-align: center;
color: white;
display:inline-block;
background:
linear-gradient(to top left,transparent 48%,#dd7758 50%) bottom left/50% 15px,
linear-gradient(to top right,transparent 48%,#dd7758 50%) bottom right/50% 15px,
linear-gradient(#dd7758,#dd7758)top/100% calc(100% - 15px);
background-repeat:no-repeat;
}
body {
background:#ccc;
}
<div class="flag-wrapper">-5%</div>
<div class="flag-wrapper">-25%</div>
<div class="flag-wrapper">-100%</div>
You can also make it working with image as background but you lose transparency:
.flag-wrapper {
background-color: #dd7758;
padding:10px 5px 30px;
margin:10px;
text-align: center;
color: white;
display:inline-block;
background:
linear-gradient(to bottom right,transparent 48%,#ccc 50%) bottom left/50.1% 15px,
linear-gradient(to bottom left,transparent 48%,#ccc 50%) bottom right/50.1% 15px,

background-repeat:no-repeat;
}
body {
background:#ccc;
}
<div class="flag-wrapper">-5%</div>
<div class="flag-wrapper">-25%</div>
<div class="flag-wrapper">-100%</div>

Use the following code, you'll also be able to add enough content in your div

box-sizing: border-box;
}
.flag {
width: 110px;
height: 56px;
margin: 0 auto;
padding-top: 15px;
position: relative;
background: hotpink;
color: white;
font-size: 11px;
letter-spacing: 0.2em;
text-align: center;
text-transform: uppercase;
}
.flag:after {
content: ' ';
position: absolute;
left: 0;
bottom: 0;
width: 0;
height: 0;
border-bottom: 13px solid white;
border-left: 55px solid transparent;
