HTML issues tagged as tab.
Elements with the role tab must either be a child of an element with the tablist role, or have their id part of the aria-owns property of a tablist.
An element with the tab role controls the visibility of an associated element with the tabpanel role. The common user experience pattern is a group of visual tabs above, or to the side of, a content area, and selecting a different tab changes the content and makes the selected tab more prominent than the other tabs.
<div role="tablist" aria-label="Sample Tabs">
<button role="tab" aria-selected="true" aria-controls="panel-1" id="tab-1" tabindex="0">
<button role="tab" aria-selected="false" aria-controls="panel-2" id="tab-2" tabindex="-1">
<div id="panel-1" role="tabpanel" tabindex="0" aria-labelledby="tab-1">
<p>Content for the first panel</p>
<div id="panel-2" role="tabpanel" tabindex="0" aria-labelledby="tab-2" hidden>
<p>Content for the second panel</p>
