The study aims to provide new knowledge about how the 100 most trafficked websites in Sweden via Google in 2024, based on a Swedish context, follow the WCAG guidelines for accessibility and specific brightness. The focus is on luminance contrast in the navigation menu on the home page, and the results are considered in relation to the law on accessibility to digital public services (SFS 2018:1937) and law on the accessibility of certain products and services (SFS 2023:254). The results are intended to guide web developers and designers in their work towards an accessible and equal internet. To carry out the studies, quantitative content analysis with elements of manual coding and technical data analysis was used. The study followed a cross-sectional design, where data was collected over a limited period of time. The approach can be compared to a document study in the sense that existing material (the website interfaces) was collected, documented and systematically analyzed. The study's results contradict previous research that the accessibility on the websites is deficient. The websites used in the study show good results, with the majority of websites reaching the highest level AAA in the WCAG success criteria. The conclusions that can be drawn from this study are that progress is being made in making websites accessible - at least in terms of luminance contrast in navigation menus - but that there is still significant work to be done to ensure accessibility for all users on equal terms.
