With this widget you can show unlimited texts during the corresponding times to your visitors.
Inspired by the <a href="https://wordpress.org/extend/plugins/time-based-greeting/" rel="ugc">time-based-greeting Plugin</a>, which gives you only the possibility to define exact four timeframes. 
With this improved Version you’re able to add unlimited timeframes.

<li>Need to make a widget sticky or fixed? Try our free <a href="https://wordpress.org/plugins/sticky-menu-or-anything-on-scroll/" rel="ugc">WP Sticky Anything</a> plugin.</li>
</ul>
Custom Sidebars works ONLY with the classic widgets screen that was used in WordPress before version 5.8. If you want to use it with version 5.8 (and above) you have to install the official <a href="https://wordpress.org/plugins/classic-widgets/" rel="ugc">Classic Widgets</a> plugin, or enable the classic widgets interface yourself. Once the classic widgets screen is activated the plugin will work the same as before.
