How to show pdf and print buttons on top corner right

The HTML generated by the plugin looks like:

<div class="readoffline-embed">
	<div class="readoffline-embed-text">Read Offline: </div>
	<div><a class="pdf" href="https://dev.local/read-offline/992/.pdf" title="Download .pdf">Download PDF</a></div>
	<div><a class="print" href="https://dev.local/read-offline/992/.print" title="Print ." onclick="read_offline_print_me();return false;">Print</a></div>
</div>

so you could add the following to your (child) theme style.css to move the buttons to the right:

.readoffline-embed {
	display: flex;
    justify-content: flex-end;
}

btw, I respond quicker to issues if you post them at GitHub

Thank you so much! I solved!
