Through the early days of the web, fluorescent textual content and pixelated gifs may very well be seen in all places. However over time, the zany, eye-catching color schemes and heavy utilization of WordArt have been changed with extra design-conscious iterations of the online.
Because the world’s historical past and tradition more and more shifted on-line, and previous internet pages have been regularly changed by newer ones, the Nationwide Library of Australia (NLA) confronted a problem relating to how it could fulfill its position of documenting Australia’s historical past and tradition.
Slightly than lose on-line data that has nationwide significance to Australia’s historical past and tradition, the NLA constructed an archive of on-line content material to point out how Australian web sites have developed over time.
