# Strikethrough using HTML5

CSS is great for styling, but not so good for providing meaning of your content. That's what HTML semantic tags are for. When you're trying to strikethrough content, there's typically a reason you're doing that. And that reason can be described using the proper HTML tag. Communicate that using <del> or <s> and give your code semantic meaning 🙌

<s>Text no longer relevant</s>

~~Text no longer relevant~~

<del>Text removed from document</del>

~~Text removed from document~~

# `<s>` vs `<del>`

Yes, they are both strikethroughs. However, they convey different meaning about the content. So they are not interchangeable. You want to pick the one that reflects what you are trying to achieve. Let's start with the definition.

# `<s>`

Use this when you are trying to represent things that are no longer relevant or not longer accurate.

✅ A good example of this is for Price Discount

<p><s>$100</s></p>
<p>$999.99</p>

On sale!
~~$100~~$899

❌ However, this tag shouldn't be used when indicating document edits. That's where <del> come in.

# `<del>`

Use this when you want to indicated something is removed from the document

✅ A good example of this is for Todo List

<p>TODO</p>

<ul>
  <li><del>Get a Job</del></li>
  <li>Become a Senior Developer</li>
</ul>

TODO
~~Get a Job~~
Become a Senior Developer

# Rule

Here's how I remember which to use. If the content represents something deleted, use <del>. And for all other instances, use the <s> 👍

# Using `<del>` with `<ins>`

Here's where I think <del> really shines. You can pair it up for <ins> and use them together to create an interface that track and record changes that happened in your document.

# Example: Text Editor

<p>My name is
  <del>Smanta</del>
  <ins>Samantha</ins>
</p>

My name is ~~Smanta~~ Samantha

# Example: Git Interface

<table>
  <tr>
    <td><del>+ function TEA() {</del></td>
    <td><ins>- function tea() {</ins></td>
  </tr>
</table>

+ ~~function TEA(){~~
- function tea(){

# `<strike>`

You might have seen the <strike> tag. This is actually the old tag that was deprecated in HTML4. It was replaced with a more semantically appropriate <s> and <del> tags, which was introduced in HTML5.

The <del> and <s> is quite well supported, even in Internet Explorer. Although some browser may still support the <strike> tags, it's best practice to avoid it 🙅‍♀️

# Accessibility Concerns

These particular tags, unfortunately, won’t be read by most screen readers. But you can use ::before and ::after property to have it announced. However best not to abuse this technique as some people deliberately disable announcing content that creates verbosity ✨

<del>

del::before,
del::after {
  clip-path: inset(100%);
  clip: rect(1px, 1px, 1px, 1px);
  height: 1px;
  overflow: hidden;
  position: absolute;
  white-space: nowrap;
  width: 1px;
}

del::before {
  content: " [deletion start] ";
}

del::after {
  content: " [deletion end] ";
}

/* MDN */

<s>

s::before,
s::after {
  clip-path: inset(100%);
  clip: rect(1px, 1px, 1px, 1px);
  height: 1px;
  overflow: hidden;
  position: absolute;
  white-space: nowrap;
  width: 1px;
}

s::before {
  content: " [start of stricken text] ";
}

s::after {
  content: " [end of stricken text] ";
}

/* MDN */
