White space (also called negative space) in neuroweb design refers to the unused area of a website that exists between the text and image elements on a page. This space can be left empty or filled with a neutral colour or pattern to create a clear separation between the different elements on the page.

Sufficient use of white space in web design can help to make a page appear clearer and easier to read. White space can help direct the user's focus to the most important content on the page by supporting the visual hierarchy and emphasising the content. In addition, white space can help to draw the user's attention to important elements such as call-to-action buttons or forms.

However, too much use of white space can also have a negative impact on the user experience by causing the content of the page to be spread too far apart and making it difficult for the user to recognise the connection between the different elements on the page.

Careful consideration between the use of white space and the grouping of content on a page can help create an optimal user experience that helps users navigate the site quickly and easily and find the information they are looking for.
