The dark navy background establishes the block’s dominant visual field, while stars and soft circular planetary shapes create the space setting around the centered content. The white heading and astronaut-themed 404 illustration share a high-contrast treatment, allowing the message and image to read as one visual group. The blue rounded “Contact us” button introduces a separate accent below the image credit without disrupting the vertical alignment.
Spacing is important to this block’s appearance. The heading sits above the illustration, the “Image from Freepik” line remains visually subordinate beneath it, and the button closes the stack with a clear separation from the attribution. That order keeps the credit from competing with the main message or the contact action. The centered alignment also gives the dark background open space around the content, rather than making the section feel crowded.
As a CSS Template interpretation, the useful focus is the appearance of this particular section: contrast, color roles, rounded treatment, alignment, and spacing can be adjusted while the heading, illustration, credit, and button retain their existing relationship. Nicepage’s Custom CSS can provide a further styling bridge when the standard visual controls do not cover a targeted treatment. The result remains one themed 404 block, not a site-wide style system.
Open this ready-made template in the CSS Template 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.
Customize the visual appearance of this ready-made template directly in the Nicepage editor. Adjust typography, spacing, backgrounds, borders, colors, positioning, and other style properties using visual controls while keeping the page layout easy to manage without writing CSS manually.
For styling requirements that go beyond the standard editor options, use Custom CSS to add targeted rules. CSS can be applied to individual elements, specific pages, or the entire website depending on the scope of the customization, while CSS classes can be used to connect custom rules with selected elements.
For projects where CSS size and page performance matter, Nicepage can export minimal CSS for each page. Instead of relying on one larger common stylesheet, each page can use a separate CSS file containing only the style rules required for that particular page. According to Nicepage documentation, these page-specific CSS files can be about ten times more compact, helping reduce unnecessary CSS and improve page loading performance.
This workflow combines visual styling with optional custom CSS and optimized page-specific CSS output, giving you additional control when a project requires it without making manual CSS editing the primary way to customize the template.
