In a similar manner as displayed in Figure 13, most graphical elements present positive trends throughout the years, which in turn lead to higher design complexity, which according to [PERSON] et al. [PERSON] et al. (2018) can lead to much coveted favorable first impressions concerning informativeness. An exception is the image map (_<map>_) graphical element. The difference between this element and the rest is that it does not adjust to fluid or responsive layout design since its dimensions are fixed. With the rise of mobile Internet, it is expected that its usage has plummeted. The video elementalso diverts from the norm, because there appears to be a fall in its usage after 2017 which has only recently been reversed. More detailed investigation through further research might shed some light on this matter, but it is noteworthy that in April 2018 was when Chrome and other Chromium-based browsers changed their autoplay policy to not allow video autoplay, in order to minimize the incentive for ad blockers and reduce mobile data consumption [36]. A major drawback of increased complexity, both in terms of structure and in terms of graphical elements, is that a large website file size negatively affects the website's loading times which can have an adverse effect on SEO [37]. However as time goes by, such technical limitations are overcome through the development of faster networks and devices with higher processing power which ensure fast loading times in increasingly large file sizes. In terms of fluid and responsive design, Figure 14 paints a clear picture, with table elements diminishing while mobile support is increasing alongside grid-based responsive frameworks. The simple approach of table elements with fluid widths was a good first step into multiple screen resolution support, but with the mobile Internet becoming more prevalent, more than that was required. It is symbolically significant that in Figure 14, the table element curve crosses the mobile scale curve sometime in 2014, which was the year that mobile Internet usage exceeded that of the PC for the first time [38]. The _mobile_scale_ variable reaches up to 90% in 2022, further reinforcing its significance. When it comes to specific frameworks, Bootstrap hovers above 30%, while Foundation is much lower. It is safe to assume that there are other ways to achieve repressiveness that our algorithm did not detect since there can be differences in framework keywords even from version to version of the same framework. Nevertheless, the rise in popularity of responsive web design tools is apparent from 2015 and onwards. RQ3: What Basic Colors and Coloring Schemes Are Prevalent in Website Hompages? Did They Change over the Years and Are There Consistent Trends That Can Be Inferred by Such Changes? As depicted in Figure 15, the number of RYB basic colors besides black and white used in website instances over the past decades is slowly but steadily increasing. Despite that, website instances only using black, white, and shades of gray were still the relative majority in 2022. Other than that, using one or two additional colors were also popular choices, and these three categories together constituted over 80% of our sample throughout the recent decades. From a usage perspective, as seen in Figure 16, white and black are, of course, the most used colors. Usage of the other basic RYB colors is much less prevalent since, as we established in Figure 15, very few are usually used in each website instance. The normalized color usage graphs in Figure 17 can be used to identify trends in color usage. White seems to be displaying significant stability with a very limited decline noticed in the latest years. On the other hand, usage of black is increasing. The graphs for other colors do not display a clear pattern and can be quite erratic on a case-by-case basis. From the warm colors, red and red-orange seem to display a positive trend, while from the cool colors purple displays a similar pattern.
