Enfold-Theme: Recommendation for error-correction and improvement

On your Website I miss a contact form for customer recommendations, so I use this form.

I am the administrator of a Hotel-Website. After installing the current Enfold-Theme, version 4.8.3, I still get errrors when checking your code by means of the W3C-CSS-Validator. I recommend to fix the following errors:
..wp-contentthemesenfoldcssbase.css:
speak: none; -> speak: never;
..wp-contentthemesenfoldconfig-templatebuilderavia-shortcodesslideshowslideshow.css:
filter: alpha(opacity = 80); -> filter: alpha(opacity=80);
..wp-contentthemesenfoldconfig-templatebuilderavia-shortcodestogglestoggles.css:
border-top-style: 1px; -> border-top-style: solid;

Furthermore I recommend the following improvement, in order to offer a more flexibel Infotext field, i. e. not to use text only but shortcode (for instance with div-tags) too:

.. wp-contentthemesenfoldincludeshelper-main-menu.php:
if($phone)
{
echo
“<div class=’phone-info {$phone_class}’>
<span>”.do_shortcode($phone).”</span>
</div>”;
}
->
if($phone)
{
echo
“<div class=’phone-info {$phone_class}’>
<div>”.do_shortcode($phone).”</div>
</div>”;
}
