CSS: Make border on pure-CSS arrow - html

Question

I have this code snippet:
.multiply-button {
display: table;
background: rgba(0, 0, 0, 0);
border: none;
color: white;
padding: 0;
}
.multiply-button-content {
display: table-cell;
background: green;
padding: 10px 9px;
border: solid 1px black;
border-right: none !important;
}
.multiply-button-arrow {
display: table-cell;
width: 0px;
height: 0px;
border-style: solid;
border-width: 20px 0 20px 12px;
border-color: transparent transparent transparent green;
}
<button id="multiply-button" class="multiply-button">
<div class="multiply-button-content">Multiply</div>
<div class="multiply-button-arrow"></div>
</button>
I need to make border on this "arrowed" button. I can easily border rectangle part (I've already did it), but how to make this border on triangle part?

Answer 1

The following should do what you need
.multiply-button {
display: table;
background: rgba(0, 0, 0, 0);
border: none;
color: white;
padding: 0;
}
.multiply-button-content {
display: table-cell;
background: green;
padding: 0 9px;
border: solid 1px black;
border-right: none !important;
position: relative;
vertical-align:middle;
height: 40px; /* double the border width */
box-sizing: border-box;
}
.multiply-button-content:after,
.multiply-button-content:before {
left: 100%;
top: 50%;
border: solid transparent;
content: " ";
height: 0;
width: 0;
position: absolute;
pointer-events: none;
border-width: 20px 0 20px 12px;
margin-top: -20px;
}
.multiply-button-content:after {
border-color: rgba(0, 128, 0, 0);
border-left-color: #008000;
margin-left: -1px;
}
.multiply-button-content:before {
border-color: rgba(0, 0, 0, 0);
border-left-color: #000000;
}
<button id="multiply-button" class="multiply-button">
<div class="multiply-button-content">Multiply</div>
</button>
This is a useful tool

Answer 3

Or much simplier :
the CSS with only one pseudo element
.multiply-button {
background: rgba(0, 0, 0, 0);
border: none;
width: 100px;
color: #FFF;
padding: 0;
overflow: hidden;
}
.multiply-button-content {
display: block;
position: relative;
background: #008000;
width: 60px;
padding: 10px 9px;
border: solid 1px #000;
border-right: none !important;
}
.multiply-button-content:before {
content: "";
position: absolute;
width: 36px;
height: 31px;
z-index: -1;
top: 0;
right: -13px;
border: 1px solid #000;
background: #008000;
transform: rotate(45deg);
}
<button id="multiply-button" class="multiply-button">
<div class="multiply-button-content">Multiply</div>
</button>

Answer 4

Since it only takes one pseudo element to make the 'point', you could use the other to make a border behind it (making it slightly bigger in size).
For example;
div {
height: 30px;
border: 2px solid black;
display: inline-block;
border-right: 2px solid transparent;
line-height: 30px;
text-align: center;
position: relative;
background: tomato;
color: white;
}
div:before {
content: "";
position: absolute;
border: 17px solid transparent;
border-left: 17px solid black;
right: -35px;
top: -2px;
z-index: 6;
}
div:after {
content: "";
position: absolute;
border: 15px solid transparent;
border-left: 15px solid tomato;
right: -31px;
top: 0;
z-index: 8;
}
<div>Arrow, Please!</div>

Answer 5

You can achieve that with :before or :after pseudo selectors. Study and adjust the example below.
.multiply-button {
display: inline;
background: rgba(0, 0, 0, 0);
border: none;
color: white;
padding: 0;
position: realtive;
}
.multiply-button-content {
display: table-cell;
background: green;
padding: 10px 9px;
border: solid 1px black;
border-right: none !important;
width: 100px;
position: relative;
}
.multiply-button-arrow {
width: 0;
height: 0px;
border-style: solid;
border-width: 20px 0 20px 12px;
border-color: transparent transparent transparent black;
position: absolute;
top: -2px;
right:-12px;
}
.multiply-button-arrow:before {
border-style: solid;
border-width: 20px 0 20px 12px;
border-color: transparent transparent transparent green;
position: absolute;
right: 1px;
top: -20px;
content: "";
}
<button id="multiply-button" class="multiply-button">
<div class="multiply-button-content">
<div class="multiply-button-arrow"></div>
Multiply</div>
</button>
