@npm-polymer/marked-element v1.4.2

<marked-element>

Element wrapper for the marked library.

<marked-element> accepts Markdown source and renders it to a child element with the class markdown-html. This child element can be styled as you would a normal DOM element. If you do not provide a child element with the markdown-html class, the Markdown source will still be rendered, but to a shadow DOM child that cannot be styled.

The Markdown source can be specified several ways:

Use the markdown attribute to bind markdown

<marked-element markdown="`Markdown` is _awesome_!">
  <div class="markdown-html"></div>
</marked-element>

Use <script type="text/markdown"> element child to inline markdown

<marked-element>
  <div class="markdown-html"></div>
  <script type="text/markdown">
    Check out my markdown!

    We can even embed elements without fear of the HTML parser mucking up their
    textual representation:

    ```html
    <awesome-sauce>
      <div>Oops, I'm about to forget to close this div.
    </awesome-sauce>
    ```
  </script>
</marked-element>

Use <script type="text/markdown" src="URL"> element child to specify remote markdown

<marked-element>
  <div class="markdown-html"></div>
  <script type="text/markdown" src="../guidelines.md"></script>
</marked-element>

Note that the <script type="text/markdown"> approach is static. Changes to the script content will not update the rendered markdown!

Though, you can data bind to the src attribute to change the markdown.

<marked-element>
  <div class="markdown-html"></div>
  <script type="text/markdown" src$="[[source]]"></script>
</marked-element>
...
<script>
  ...
  this.source = '../guidelines.md';
</script>

Styling

If you are using a child with the markdown-html class, you can style it as you would a regular DOM element:

.markdown-html p {
  color: red;
}

.markdown-html td:first-child {
  padding-left: 24px;
}
