404 not found block Website Mockup
The Split Error Composition Needs Careful Width Review
The block's main visual dependency is the balance between the left message group and the right server illustration. At wider screen sizes, the large pixel-style 404 number, explanatory text, and Go to homepage button can occupy one focused column while the illustration supplies a separate visual anchor. A responsive mockup review should confirm that this relationship remains clear rather than allowing one side to overwhelm the other.
Narrower screens may change how the two columns stack or compress. The not-found explanation should wrap without separating its meaning from the 404 heading, and the button should remain easy to locate beneath the message. The server illustration also needs enough scale to remain recognizable without forcing excessive vertical space or pushing the return action too far away from the text. These are the key presentation relationships to inspect across screen widths.
The purple-to-teal gradient should continue to provide sufficient contrast for the cyan and white typography in each arrangement. The outlined button needs to remain visible against the changing balance of background and illustration. Because the interaction is static, the review centers on layout, text flow, image scale, spacing, and visual hierarchy rather than changing states. The result should still read immediately as one coherent unavailable-page section on large and narrow displays.

Preview and Refine This Website Mockup
Review the Design Across Devices
Use Responsive Modes to see how the website design appears on Large Screens, Desktops, Laptops, Tablets, and Phones. Switch between the available views to compare the same layout at different screen widths and review how typography, images, spacing, navigation, and other content adapt to each device.
Adapt the Mockup for Different Screens
Nicepage provides responsive web design tools for adjusting individual device views when the initial layout needs refinement. You can customize Mobile Views separately, change element sizes and positions, adapt Grids, Lists, and Galleries, and hide selected Elements or Blocks on particular screen sizes. This makes it possible to develop a responsive website mockup instead of evaluating the design at only one fixed desktop size.
Preview the Website Without Editing Controls
Use Live Page / Preview to review the design with the editing interface removed from view. Instant Preview can hide the Page Navigator, Property Panel, selections, and frames, making it easier to evaluate the overall presentation, content hierarchy, and responsive layout as a visitor would see them.
This workflow makes the template useful as a responsive website mockup for visualizing, comparing, and refining how the same website design will appear across different screen sizes.
