`$.fadeIn()`

This function will require at least 1 arguments, but you can give it 3 arguments, which are:

element
i (optional), this is the opacity that will be added every frame. Its default value is 0.1
display (optional), this will be the display method. By default its value is block
Example:
HTML:
```
<div class="fade">Hello World 🌎!</div>
<button>Show the div</button>
```
JS:
```
var div = $.select(".fade")
$.hide(div)
$.on($.select("button"), "click", function () {
  $.fadeIn(div)
})
```
$.fadeOut()
This function is the exact opposite of the $.fadeIn() function. As the $.fadeIn() function, it will require at least 1 argument, but you can give 2 arguments, which are:
element
i (optional), this is the opacity that will be removed every frame. Its default value is 0.1

I don't think 🤔 you'll need any example of this function, because it works like the previuous function.

Don't hesitate to ask your questions ⁉️ in the issue part 😁
