404 page not found Html Code Example

The section is an unavailable-content message built around the 404 status, a direct heading, a supporting explanation, and a “go to home page” action. A white text card occupies one side of the two-column split, while a technical error illustration fills the other. The bright blue background separates the block from surrounding content and gives the error state a recognizable setting. Because the layout already distinguishes the message and illustration regions, the section has clear areas where project-specific functionality could be considered without changing its basic communication.

The Text Card Leaves a Defined Area for Optional Extensions

The white card already contains the block’s essential recovery message: the 404 code identifies the status, the heading states that the requested page does not exist, and the supporting sentence explains that the address may have been mistyped or the page may have moved. The black “go to home page” button then supplies a direct route toward recovery. Beside it, the technical illustration acts as visual explanation rather than another information-heavy content area.

That separation creates logical extension points if a project needs functionality beyond the existing message. A custom element could be considered near the action or within the text-card region for a project-specific search prompt, support reference, or another recovery option, provided the added feature serves the same unavailable-content situation. The illustration area could also remain visually reserved while custom content is kept within the message region. This is an optional extension around the block’s real content, not a claim that custom code is already present. The existing two-column relationship should remain the organizing principle so any added functionality supports the 404 explanation instead of competing with the status, supporting text, or home-page action.

Extend This Page With Custom HTML Code

Insert Code With the HTML Element

Use the HTML Element to add custom code directly to a Block in the Nicepage editor. Enter the required markup in the Code field when the page needs content or functionality that is not available through the standard page elements.

Place the HTML Element in the Layout

Treat the HTML Element as part of the visual page composition. Adjust its position, width, height, alignment, and margins to place the custom content where it belongs alongside text, images, buttons, and other elements. This makes it possible to combine visually edited sections with project-specific code without separating the custom element from the rest of the layout.

Add HTML, CSS, JavaScript, and External Components

The HTML Element supports HTML, CSS, and JavaScript, allowing you to extend the page with custom markup and interactive functionality. It can also be used to embed custom code and third-party components, such as social feeds, advertising code, widgets, or other external functionality required by the project.

This workflow makes the template useful for projects that need a visual page editor together with custom HTML code, JavaScript, embedded components, and functionality beyond the standard page elements.
