Creating a "read more" link that extends the content on the page

Question

I would like to create a read more link that would extend a paragraph already being shown to reveal the entire text on the same page. If this could be solves with HTML5 and CSS, I would like that, but I assume some type of script will be needed.

For example:

Example text

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam porttitor feugiat ipsum quis ullamcorper. Nullam vitae velit vitae tortor semper tempor ac vitae magna. Maecenas a ullamcorper neque. Aliquam vitae tortor luctus nisi rutrum eleifend non non leo.

Sed eleifend lectus id semper accumsan. Sed lobortis id ligula eget blandit. Integer interdum iaculis nunc, sed porttitor magna tincidunt in. Interdum et malesuada fames ac ante ipsum primis in faucibus. Aliquam lobortis accumsan tempor. Aliquam sollicitudin pulvinar est, quis convallis tellus.

I would like the normal text to be shown with the "Read More >>" link below, and then the bold text will be revealed after clicking the link.

I also want to have an image in the hidden section, would this be possible?

Thanks in advance.

A vanilla JS alternative:

The HTML:

<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam porttitor feugiat ipsum quis ullamcorper. Nullam vitae velit vitae tortor semper tempor ac vitae magna. Maecenas a ullamcorper neque. Aliquam vitae tortor luctus nisi rutrum eleifend non non leo.</p>
<div id="more" style="display:none;">
    <p>Sed eleifend lectus id semper accumsan. Sed lobortis id ligula eget blandit. Integer interdum iaculis nunc, sed porttitor magna tincidunt in. Interdum et malesuada fames ac ante ipsum primis in faucibus. Aliquam lobortis accumsan tempor. Aliquam sollicitudin pulvinar est, quis convallis tellus.</p>
    <img..../>
</div>
<a href="javascript:showMore()" id="link">Read More >></a>`

The JS:

function showMore(){
    //removes the link
    document.getElementById('link').parentElement.removeChild('link');
    //shows the #more
    document.getElementById('more').style.display = "block";
}
