# 在 Hackmd 中加入 Like Coin 贊助連結

在hackmd前方加上CSS，如下：

<style>
.likecoin-button {
  position: relative;
  width: 100%;
  max-width: 485px;
  max-height: 240px;
  margin: 0 auto;
}
.likecoin-button > div {
  padding-top: 49.48454%;
}
.likecoin-button > iframe {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}
</style>

之後在想要加入按鈕的地方加上HTML：

<div class="likecoin-embed likecoin-button">
  <div></div>
  <iframe scrolling="no" frameborder="0" src="https://button.like.co/in/embed/{{Like ID}}/button?referrer=hackmd.io"></iframe>
</div>

## 範例：

<style>
.likecoin-button {
position: relative;
width: 100%;
max-width: 485px;
max-height: 240px;
margin: 0 auto;
}
.likecoin-button > div {
padding-top: 49.48454%;
}
.likecoin-button > iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
</style>

<div class="likecoin-embed likecoin-button">
<div></div>
<iframe scrolling="no" frameborder="0" src="https://button.like.co/in/embed/billy3321/button?referrer=hackmd.io"></iframe>
</div>
