I use this calendar <input type="date">
I researched it but so far I have not found anything about its css formatting. I wanted to know if it's possible to customize it and how I can do it.
If there are other calendars I'm open to suggestions.
<input type="date" class="form-control input-titulo" id="description-input" /> Below I've put an example of using datepicker of jquery with its base theme, this link you can see css of the base theme (just search for datepicker and you will see some of its classes and properties).
//http://api.jqueryui.com/datepicker/
//https://jqueryui.com/datepicker/
$( function() {
$( ".datepicker" ).datepicker();
});<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script><scriptsrc="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<div>
Data:
<input type="text" class="datepicker">
</div>
