Which Page Division Method Fits Your App? Lines, Background Bars, Shadows, and Whitespace Explained

With the rise of minimalism, de‑line (removing lines) has become a design trend, and many products replace lines with spacing to separate pages. While many platforms showcase excellent examples, not every app is suitable for whitespace division; each product has its own characteristics. This article discusses several common page‑division types, their features, and appropriate usage.

1. Divider Line

Divider lines are the most common form in design. Whether full‑width or partial, they help users understand content hierarchy, distinguish modules, and separate related content. The line’s color depth directly affects the strength of division; today’s product lines are usually light, making them less obtrusive and allowing smoother browsing, which improves efficiency compared to other division methods.

In everyday design, text‑heavy products like Toutiao, Zhihu, and QQ Mail still use divider lines to separate page content because they need dense information display, allowing users to quickly browse more content.

2. Background Bar Division

Background‑bar division can be seen as a container holding many independent cards; differing card colors and background colors create visual separation. Essentially, it uses colored blocks to divide the page, which creates a stronger visual blockage, slows reading speed, and increases the time users spend on each module.

For products with many business modules and large information volume, this division helps organize content and reduces user comprehension cost. E‑commerce platforms such as Taobao, JD.com, and Xianyu use it extensively.

3. Shadow Division

Shadow division emerged with the rise of card‑style design. Adding shadow lifts the card on the Z‑axis, creating visual hierarchy and highlighting information, quickly attracting user attention.

Examples include Xianyu’s message top area, Shuqi Novel’s activity module, and Beike’s homepage entry points. However, shadows add visual elements; overuse can become visual noise. Therefore, this style suits pages with a clean visual layout or pages with abundant information that need to highlight important modules.

4. Whitespace Division

Most mainstream apps now use whitespace division. It separates content through spacing rather than lines, representing an upgrade of the visual container system. Viewed in X, Y, Z dimensions, whitespace reduces Z‑axis layers, making the page flatter and more breathable, while larger gaps improve overall readability.

Designs like Xiachufang, Qingting FM, and Litchi FM have a simple tone and are image‑centric; the inherent separation of images works well with whitespace, reducing interference from additional elements and making the page more airy and clean.

Summary

Not all products are suitable for whitespace division because it lengthens pages and reduces space utilization; when users need to browse large amounts of information efficiently, divider lines are preferable. For pages with many business modules and complex information, background‑bar division helps organize content. Ultimately, the choice of division method should serve the specific product type rather than blindly following trends.

That’s all for today’s summary—do you now know which division style fits your app?
