The block depends on the visual balance between a left text region and a right illustration. At wider sizes, the “404 error” heading, explanatory paragraph, and “Go to homepage” button should remain grouped and easy to scan, while the image retains enough scale to act as a visual counterpart. The pale blue background should continue to connect both regions without making the text or illustration appear detached.
At narrower widths, the key mockup questions concern column stacking, paragraph wrapping, and the button’s position in the reading sequence. If the illustration moves below the message, it should still support recognition without pushing the recovery action too far away. If the two regions remain side by side, the text must retain sufficient width for the explanation and the heading must not overpower the available space. Generous spacing should be reviewed as well, since it controls the transition between the error state and the recovery route.
The section is static, so responsive evaluation focuses on presentation rather than interaction behavior. A useful mockup review checks whether the dark heading, turquoise button, and colorful illustration retain their intended hierarchy across screen sizes. The surrounding page may change, but this block should continue to read as one coherent error message with one clear destination.
Open this ready-made template in the Website Mockup Builder and customize it visually in the Nicepage editor. Replace demo content, edit page sections, and adapt the design to your project without rebuilding the template from scratch.
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.
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.
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.
