No styles for classes like ft00, ft01 etc.

[KMV1]

Hi!

My output html file has classes like ft00 etc:
<p style="position:absolute;top:1218px;left:638px;white-space:nowrap" class="ft00">Some text</p>

but it has not styles for this class. So font-size is incorrect in the result. And html page looks not like an input pdf.

While running a script there are some errors:

PHP Warning:  count(): Parameter must be an array or an object that implements Countable in /root/vendor/paquettg/php-html-parser/src/PHPHtmlParser/Selector.php on line 171
PHP Warning:  count(): Parameter must be an array or an object that implements Countable in /root/vendor/paquettg/php-html-parser/src/PHPHtmlParser/Selector.php on line 172

How I can fix it and how to get correct styles?
