If you are reading this, you probably realized that having a sidebar on mobile devices is not necessary. This Itechguide teaches you how to hide the sidebar for mobile in WordPress.
Overview
For most WordPress themes, when you add sidebar widgets – primarily intended for larger screens – these sidebar widgets also display on mobile devices.
In the first instance, on a mobile device, a sidebar is no longer a “sidebar” but more of a “bottom bar”. Furthermore, on mobile devices, sidebars display after the main post – defeating the purpose of having them.

Step 3: Clear Cache and Test
To be clear, the last section effectively hid the sidebar for mobile devices in WordPress. However, I decided to add this section because if you use a caching plugin or CDN, you will need to clear the cache for the changes to take effect immediately.
After clearing the cache in the caching plugin and/or CDN, open the website on a mobile device. If the change does not reflect immediately, use Incognito (Chrome) or InPrivate (Microsoft Edge).

thank you so much its working
The sidebar div “ID” you found (.sidebar) is actually a class, not an ID. That’s why you select it using “.” instead of “#” (“#” is the ID selector). The div you found only has a class, not an ID.
Thanks for the helpful article. It really makes it pretty easy to identify the codes for your sidebar and how you can stop it displaying on mobile.
With all the drive to make websites faster, its strange that there are no default options available in WordPress.
Appreciate your work 🙂
It shouldn’t be a surprise. The code you have in the post for the @media query is not structured right. It IS missing brackets.
Tomasz has it done the RIGHT way.
Plus, using CSS to hide a big chunk of the page is a horrible idea. all the processing for it STILL happens – it’s just never shown to the user in the browser.
Thanks for the feedback.
I had to wrap the sidebar class code in an extra pair of braces to make it work:
@media (max-width: 768px) {
.sidebar {
display: none;
}
}
It is a bit strange that you needed to include the extra braces. However, I am glad you made it work for you and thanks for staring!
