Ask David! Question
“I’ve been using Sitely on my Mac to build my site, but I’m hitting a total wall with the mobile version. It looks fine in the editor, but the layout completely shatters and overlaps the second I export it. I did some googling and found UltimateWB recommended as a solid alternative where I can still use my own web hosting. I want to know: Is this broken mobile export just an inherent flaw with how Sitely handles design, and does UltimateWB actually solve it?”
To answer your question directly: In many cases, the kinds of Sitely layout issues you describe stem from the limitations of fixed-canvas design architectures rather than user error – and UltimateWB addresses this fundamentally differently.
The reason many users hit this wall is that Sitely (previously Sparkle app) approaches web design more like a static print canvas, relying heavily on absolute positioning and breakpoint-specific layouts. UltimateWB, by contrast, is engineered with a fluid architecture that handles responsive scaling natively.
Instead of forcing you to manually build, duplicate, and maintain separate, conflicting layout copies for every single device viewport, a single unified layout adapts automatically. You get clean, responsive code that loads properly across all screens without the maintenance nightmare – all while fully retaining your right to independent web hosting. The UltimateWB built-in Responsive app makes this process easy.
You can host on your own server like you said, as UltimateWB is a downloadable website builder you can install where you would like. And, you can also choose to host with UltimateWB for a fast, high-performing, optimized server, and perks like free SSL and custom emails.
Here is a technical look at exactly why that fixed-canvas approach can cause complications on the mobile version, and what is happening behind the scenes of those export errors.
Common Sitely & Sparkle Mobile Symptoms
When a desktop-based visual builder attempts to force a fixed layout onto fluid phone screens, users often run into a specific set of frustrations:
- The Shifting Layout: The desktop layout looks perfectly aligned, but elements shift unpredictably or overlap when viewed on an iPhone or Android screen.
- The Update Disconnect: Changing a headline or moving an image on the desktop view doesn’t automatically flow to the mobile view, requiring you to manually rebuild or shift elements layout-by-layout.
- The Vanishing Mobile View: The site displays correctly on a desktop browser, but loading the live URL on a smartphone may render in a way that does not match the intended responsive layout setup.
- Hidden Performance Drain: Pages can feel sluggish on mobile devices over cellular networks, even after hiding heavy desktop images using the editor’s device visibility toggles.
Here is what is actually happening under the hood when a local canvas export fails to render cleanly on mobile devices.
1. Absolute Coordinates vs. The Fluid Web
Modern web layouts are designed to wrap, shrink, and scale dynamically across devices – from compact phones to massive desktop monitors. Content is meant to flow fluidly inside relative containers. That is the definition of responsive.
Because Sitely functions like a desktop publishing application (similar to Apple Pages or Adobe InDesign), its underlying layout engine relies heavily on absolute positioning. Instead of telling a browser to size a text container relative to the viewport width, the software compiles hardcoded CSS that places elements a fixed number of pixels from the top and left margins.
When those rigid, absolute coordinates hit a fluid mobile screen, the layout struggles to adapt. Text boxes can overlap adjacent images, buttons migrate off-screen, and containers can bleed past the viewport boundaries.
The Accessibility Compromise: Verified in Sitely’s Own Webpage Source
This fixed-canvas paradigm introduces a critical tradeoff regarding user accessibility. On a naturally fluid web, if a mobile visitor has their smartphone accessibility settings set to “Large Text,” a responsive container scales and flows automatically to accommodate it.
But in a rigid coordinate layout, if typography scales up, it instantly breaks out of its absolute container boundaries and shatters the surrounding visual grid.
We don’t have to speculate about this behavior – we can see it directly inside the production page source of Sitely’s own official corporate website. To force the live browser to respect its rigid layout boundaries and prevent text overlapping, their flagship site code injects aggressive, global CSS resets specifically engineered to override and block native browser-level text scaling:
CSS
html,body{-webkit-text-zoom:reset !important}
p,span,h1,h2,h3,h4,h5,h6,a,li,button{margin:0;word-spacing:normal;word-wrap:break-word;-ms-word-wrap:break-word;pointer-events:auto;-ms-text-size-adjust:none !important;-moz-text-size-adjust:none !important;-webkit-text-size-adjust:none !important;text-size-adjust:none !important;max-height:10000000px}
While this defensive coding shields their flagship layout blocks from shifting on a phone, it does so by stripping away native user accessibility options. This under-the-hood reality perfectly illustrates why treating the web like a static piece of print paper requires actively disabling the natural, adaptive mechanics of the mobile browser itself.

2. The Multi-Layout Breakpoint Trap
To address mobile formatting, canvas builders require you to manually design separate, independent layout copies for different device widths (such as Desktop, Tablet, and Smartphones).
This introduces two major architectural limitations:
- Manual Layout Maintenance: Because the content structure doesn’t flow naturally down the page, making a major edit to your primary desktop view means you must switch layouts and manually re-arrange, resize, or reposition those same assets for your mobile viewports.
- DOM Bloat and Page Weight: In many canvas-based workflows, when you hide a heavy desktop asset on a mobile layout, that element can remain embedded in the exported HTML markup via properties like
display: none;. Unless the platform handles advanced conditional loading natively, mobile visitors are still forced to download that unnecessary page weight, impacting mobile page speed and performance metrics.
3. Local Compilation vs. Live Server Integration
Unlike browser-based platforms or cloud-native environments that render pages dynamically from a live database, desktop website builders exist entirely as local project files on your hard drive. When you click “Publish” or “Export,” the software runs a local compilation process to translate your visual canvas into static HTML and CSS files, which you then upload to a web host via FTP.
This creates a fragile gap between the controlled local editor preview and the live web server environment:
- The Editor vs. Browser Disconnect: Inside the local desktop application, you are viewing a highly controlled, simulated preview. But on the live web, a user’s phone might have an unexpected viewport width, unique device pixel scaling, or custom browser font settings. Because the exported code relies on hardcoded layout definitions rather than fluid, relative container rules, these real-world browser variations cause elements to overlap or shift unpredictably—even if everything looked flawless inside the editor.
- File Structure & Path Redirects: True responsive web design happens natively inside the browser using fluid code rules. Because a desktop canvas builder relies heavily on rigid, breakpoint-specific layout logic, inconsistencies between exported CSS files, aggressive browser caching behavior, or server-side path redirects can lead to mobile layouts failing to render correctly.
- The Legacy Subfolder Workaround: When users hit a total wall with mobile rendering, some resort to the old-school workaround of exporting an entirely separate mobile project file into a distinct
/mobile/or/m/subfolder. This introduces complex, manual device-detection routing. These setups break easily if server-side redirect rules aren’t perfectly aligned, hurting both user experience and SEO mobile indexing.
Why Is Sitely Even Popular?
It’s popular because it appeals to a very specific demographic: graphic designers who prefer visual desktop publishing workflows over traditional web development concepts such as document flow, relative containers, and responsive layout systems.
They want a tool that behaves exactly like Adobe InDesign, Illustrator, or Apple Pages. They want to grab a text box, drag it to pixel coordinate X: 142, Y: 580, drop it, and have it stay exactly there. For many users, manually maintaining separate mobile layouts is an acceptable tradeoff for preserving pixel-level visual control without having to learn how HTML boxes, margins, and fluid layouts function.
The Sitely Cost vs. Infrastructure Reality
Price shouldn’t be measured just by the upfront sticker, but by what you actually own at the end of the day.
Sitely charges a flat fee ($79.99 to $119.99) strictly for a local desktop license on your Mac. While it gets you out of the SaaS monthly loop, you are still fully responsible for sourcing your own external web hosting, setting up your own SSL certificates, and managing local flat files.
UltimateWB approaches pricing based on structural freedom. If you want a hands-off environment with lower up-front fees, the Cloud Plans bundle the hosting and software together, scaling cleanly by server resources ($10 to $70/month depending on the software version and tier). If you prefer complete digital autonomy, you can buy a lifetime software license outright (ranging from $19 to $249 based on features) and host it anywhere that satisfies the server requirements – or pair it with an UltimateWB web hosting plan (starting at $4.99/month). Because it isn’t a rigid, locked-down ecosystem, you can start small and upgrade your hosting resources seamlessly as your traffic scales, without ever losing a shred of backend control.
Balancing Visual Control with Code Cleanliness
The desire to maintain an independent web presence without relying on a complex plugin ecosystem or locked-in SaaS platforms is completely understandable. However, trading backend software updates for manual layout rebuilding doesn’t solve the core issue of digital autonomy.
True autonomy means running your site on an approach that handles responsiveness natively.
Some website platforms, including UltimateWB, take a different path by building responsive behavior directly into the core system engine. Instead of forcing you to build, track, and maintain separate, conflicting layout copies for every single page, a single unified layout adapts fluidly across all devices automatically. The functionality is completely built-in, the underlying code remains lightweight, and you retain complete database ownership without dealing with fragile local export compilers or shifting mobile coordinates.
Sitely’s canvas-based approach offers appealing visual freedom for offline layout projects. But the web is not a printed page. Understanding the architectural tradeoffs of a fixed-canvas builder can help you determine whether a desktop-compiled workflow is the right long-term approach for a mobile-first web environment.
FAQ: Sitely Mobile Export Issues
Why does my Sitely site look broken on mobile after export? Because Sitely’s design workflow treats the web like a fixed canvas, it relies heavily on absolute positioning and breakpoint-specific layouts. When a design is tied to explicit positioning rules rather than fluid, adaptive containers, maintaining content parity across dozens of unpredictable mobile screen sizes becomes an uphill battle.
Does Sitely support automatic responsive web design? No, it does not handle responsiveness automatically. Instead of a fluid box model where content wraps natively, it uses a manual breakpoint system. To make a site look right on mobile, you are required to manually duplicate your content and physically rearrange your layout for separate device viewports.
Why is a fixed-canvas architecture inherently limited on the mobile web? Because the web is not a static piece of print paper; it is entirely fluid. A fixed-canvas builder treats the screen like a rigid drawing board with exact pixel boundaries. When that hardcoded, desktop-compiled code is forced onto thousands of different mobile viewports, the lack of native, fluid box-model structure means elements can overlap, overflow, or shift out of alignment.
