404 error page Website Mockup
Review the Illustration, Text Stack, and Button Row Across Widths
The block’s mockup review should begin with the relationship between the upper illustration and the centered text stack. The construction-barrier image with its visible 404 sign carries much of the visual weight, so its scale should remain proportionate to the “Page not found” heading rather than overwhelming the explanatory paragraph. The “Oops!” label, heading, paragraph, and attribution note also need enough vertical separation to preserve the intended reading order.
The lower action row is the main width-sensitive relationship. “Go Home” and “Contact Us” are designed as side-by-side choices, so a narrow presentation should be checked for button width, label wrapping, horizontal spacing, and whether the pair still reads as one action group. The light blue-gray background makes uneven alignment easy to notice around the centered stack. Since the interaction is static, visual evaluation can focus on image scale, text wrapping, vertical rhythm, and the transition from the message to the buttons. In a website mockup, this section should be assessed as one responsive unit inside a broader page presentation, not as evidence of unconfirmed behavior. The goal is to keep the error state compact, legible, and visually balanced at different screen widths.

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.
