Bug report: SEO Optimization

After publishing the page containing slider Accessibility has dramatically decreased.

Here is the list of discovered problems with PageSpeed Insights from Google:

1. [aria-*] attributes do not match their roles (related to active slick dot)

<li aria-hidden="false" role="presentation" aria-selected="false" aria-controls="navigation01" id="slick-slide01" class="slick-active">

2. Elements with an ARIA [role] that require children to contain a specific [role] are missing some or all of those required children (related to slick dots list and active slick dot)

1 2 3 4
<ul class="slick-dots" style="" role="tablist">

2
<li aria-hidden="false" role="presentation" aria-selected="false" aria-controls="navigation01" id="slick-slide01" class="slick-active">

3. button, link, and menuitem elements do not have accessible names (it’s about previous and next slick arrows of slider).

div.wppsac-wrap > div#wppsac-post-carousel-1 > span.slick-prev
<span class="slick-prev slick-arrow" data-role="none" role="button" style="">

div.wppsac-wrap > div#wppsac-post-carousel-1 > span.slick-next

<span class="slick-next slick-arrow" data-role="none" role="button" style="">

4. [aria-hidden="true"] elements contain focusable descendents (related to slick dots)

1
<li class="" aria-hidden="true" role="presentation" aria-selected="true" aria-controls="navigation00" id="slick-slide00">

<button type="button" data-role="none" role="button" tabindex="0">

<button type="button" data-role="none" role="button" tabindex="0">

5. ARIA input fields do not have accessible names (related to slick tray)

<div class="slick-track" style="opacity: 1; width: 7686px; transform: translate3d(-2562px, 0px, 0px);" role="listbox">
