Your WordPress site looks right on desktop, but the columns become cramped and the main button disappears below an oversized image on your phone. You do not necessarily need a rebuild or another responsive-design plugin. Start with the broken section.

Quick answer: To make a WordPress website mobile friendly, find the layout that fails at phone widths, fix it, and check navigation, buttons, and forms. Use your editor’s responsive controls when they solve the problem. Below, you’ll find a native Gutenberg fix and an alternative workflow with Frontman when you would rather describe the change than find each setting.

Jump to the Gutenberg fix or watch Frontman edit a WordPress page.

Diagnose the mobile problem first

Responsive design means a page adapts to different screen sizes. That does not mean every desktop layout should be squeezed onto a phone unchanged. A desktop row of images and text may sensibly become a vertical stack—but the order, spacing, or image sizes can still make the mobile version hard to use.

Start with the page where visitors encounter the problem:

Open the page in the WordPress editor and use its mobile and tablet preview options, if available.
Open the page in a browser at a narrow width, then check it on a phone when possible. WordPress.com’s guide also recommends checking the live site in a browser or on a mobile device for a more accurate preview.
Look for specific failures: horizontal scrolling, clipped text, images that dominate the screen, columns in a confusing order, buttons that wrap awkwardly, or a menu that is difficult to use.
Note the page URL and the element that needs attention. A specific request—“stack these cards on mobile, with the heading before the image”—is more useful than “make the site responsive.”

WordPress provides built-in responsive controls in some editors and themes. Depending on your setup, you may be able to stack content, adjust typography, change menu behavior, or set different styles for different screen sizes. See WordPress.com’s mobile-friendly site guide and Learn WordPress’s responsive-site lesson for examples.

Match the symptom to the first check

Mobile problem	First thing to inspect	First fix to try
Horizontal scrolling	An image, embed, or container wider than the page	Remove an unnecessary fixed width or use the element’s responsive width control.
Cramped columns	Whether the section stacks at narrow widths	Enable mobile stacking where your editor provides it.
Oversized headings	Font size, line height, and text wrapping	Use responsive typography controls if available, then check desktop too.
A button below a huge image	Image dimensions and the section’s reading order	Reduce the mobile image size or adjust the mobile arrangement where supported.
A difficult menu	Whether it opens and its links fit on screen	Check the theme or navigation block’s mobile menu settings.

These are starting points, not universal settings. Gutenberg, Elementor, and individual themes expose different controls.

For Avada pages, inspect the Containers, Columns, and Design Elements in Avada Live Builder before applying an editor-specific fix.

Fix cramped Gutenberg columns without another plugin

If the section uses WordPress’s core Columns block, check Stack on mobile first. WordPress enables this setting by default. A disabled setting can leave columns side by side on a narrow screen.

Before changing a published page, use a staging copy and a backup you know how to restore.

Open the affected page in the block editor.
Open List View and select the parent Columns block, not an individual Column or its text.
Open the block settings sidebar. In the Settings tab, enable Stack on mobile if it is off.
Save the staging page and open its front end at phone width.
Check that the columns stack, the content reads in the right order, and nothing scrolls sideways.
Compare tablet and desktop widths before promoting the change through your normal publishing process.

This uses the core Columns block’s documented setting. It does not change an Elementor section or a third-party columns block. If stacking is already enabled, inspect the child blocks for fixed widths or theme CSS overrides instead.

The target result is stacked content on mobile with the intended desktop columns intact. Stacking alone does not set a different mobile reading order.

Choose the fix that matches your site

Choose this	When it fits
WordPress, theme, or builder controls	Your editor exposes the setting you need, such as the core Columns block’s mobile stacking control.
Frontman	You can describe the mobile problem but want an agent to inspect the page and help implement the fix through supported WordPress tools.
A developer or theme author	The work involves complex theme-level CSS, custom functionality, or a feature outside the supported tools.

We built Frontman. Use familiar native controls when they already solve the problem. Frontman is an alternative when you can describe the result but do not know which editor operations it needs.

Watch the WordPress editing workflow

Before you install, see what editing beside the page looks like. This existing demo shows a FAQ-title change, not a mobile-layout repair:

Select “What Is A Lightning Strike?” on the page.
Request a more engaging title.
Review the new title, “Lightning Strikes: The Secret Weapon That Forces Markets To Pay Attention,” beside the conversation.

Demo from Frontman’s WordPress.org plugin listing. It shows a visible text edit and review, not evidence of mobile-layout correctness or unchanged desktop behavior.

Install Frontman on your staging site →

Frontman needs administrator access, sign-in, service access, and your own supported AI provider with separate costs. See the requirements before you start.

Describe the mobile fix instead of hunting for settings

For the same cramped-columns problem, you can ask Frontman to inspect the section and make the supported edit. The goal stays the same: readable stacked content on mobile without an unintended desktop change.

Frontman connects that visual feedback to editing on the existing site. Its browser feedback loop gives the agent screenshots, DOM inspection, and desktop, tablet, and mobile viewports. On WordPress, dedicated tools let it work with Gutenberg blocks, Elementor content when active, and active-theme Additional CSS, among other supported surfaces.

The workflow is inspect → change → check:

Inspect the mobile page. Use the preview to identify the awkward section and its underlying structure.
Make a focused edit. Describe the stacking behavior you want, keeping the request within the page’s supported editing surface.
Check the result. Inspect the narrow-screen layout again, then compare tablet and desktop views for unintended changes.

The benefit is not another set of responsive controls. It is help translating the change you can describe into WordPress operations, with the page beside the conversation. Frontman does not expose every theme or plugin setting; check the supported WordPress operations before planning a larger change.

Before you start

Access: WordPress 6.0 or later, PHP 7.4 or later, and an administrator account with the manage_options capability.
Account and costs: GitHub or Google sign-in, Frontman service access, and your own supported AI provider. Provider costs are separate. Frontman does not include a built-in model credential. See the provider connection guide.
Staging and backup: Use a staging copy and a backup you know how to restore. WordPress writes affect the connected installation. Published content can change immediately; the live preview is not a universal approval gate.

Make one focused change

Install the plugin. In WordPress admin, go to Plugins → Add New Plugin, search for Frontman - AI Website Editor, then install and activate it. You can also use the plugin page in the WordPress Plugin Directory.
Open Frontman from the admin menu. Sign in if prompted, return to the WordPress admin, and connect your supported AI provider.
Open the affected page’s preview. Describe the desired mobile behavior and what should remain unchanged.
Inspect the result before promoting it. Check mobile, tablet, and desktop layouts. Promote the staging change through your normal WordPress process only after reviewing it.

For the cramped-columns example, adapt this request to your page. This is a suggested prompt, not the recorded request from the title-edit demo:

Inspect this Columns block and its mobile stacking setting. Make the columns stack on narrow screens without horizontal overflow. Keep their desktop arrangement unchanged. Explain the planned edit before changing the section.

Your acceptance criteria are concrete: the columns stack on mobile, the content remains readable, and the section has no horizontal scrolling. The desktop arrangement must remain intact. Check each one against the actual page.

Before you publish: check the experience and recovery path

Check more than whether the page now fits inside a narrow viewport:

Layout: Look for horizontal scrolling, overlap, clipped content, and awkward gaps.
Reading order: Make sure headings, images, and supporting text appear in a sensible sequence.
Navigation: Test that the mobile menu opens and that its links are usable.
Buttons and forms: Check that controls fit, remain readable, and can be used on a phone.
Images and text: Check that images scale without losing important context and that text is not cut off.
Multiple widths: Resize the browser or use responsive design mode in developer tools to catch issues between phone and tablet widths. A single preset does not represent every screen.

Editor previews are useful, but also inspect the actual page in a browser and on a phone when possible. For broader checks, Browserling offers responsive testing across screen sizes and browsers. It complements editing rather than replacing it.

If a change is not visible, caching may be involved; Frontman’s WordPress guide documents supported cache inspection and cache-clear requests.

A better layout is not the same as a faster site. For Elementor sites, diagnose page speed separately. Large images, hosting, and caching can still affect load time. A visual change does not guarantee search rankings, accessibility compliance, or correct behavior across every device and browser.

Frontman’s WordPress changes also have different recovery options. Some tools require explicit confirmation, and Elementor changes have Frontman rollback snapshots. But there is no plugin-wide one-click undo for Gutenberg, menus, templates, widgets, settings, or other supported surfaces. Use WordPress revisions or trash where applicable, and rely on a verified backup when needed. The WordPress integration guide explains the limits by change type.

Fix one mobile layout issue first

Start with the section that is hardest to use on your phone—not a whole-site redesign. Use the native control if it solves the problem. If you want Frontman to help implement the change, start on staging and check the result at phone, tablet, and desktop widths.

Install Frontman on your staging site →
