Justify text in a div with width 100% - 60px

I have a

#menu {
  width: calc(100vw - 60px);
  left: 30px;
}

How can the words be justified in the available space?

I'm tryin the

text-align:justify

but it doesn't work.

I assume you mean the text. This is because text-align: justify doesn't justify the last line of a block of text. One workaround is to add a css generated content item that acts like an inline text item but stretches the full width of the container like so:

#menu:after {
  content: '';
  display:inline-block;
  width: 100%;
}

#menu{
font-family: Arial;
font-size:22px;
width: calc(100vw - 60px);
left: 30px;
text-align: justify;
text-justify: inter-word;
position:fixed;
}

#menu:after {
  content: '';
  display:inline-block;
  width: 100%;
}

<div id="menu">
