HTML and CSS Reference
In-Depth Information
In 2004, Ian Hickson, the editor of the HTML5 spec, mined
one billion web pages via the Google index, looking to see
what the “real” Web is made of. One of the analyses he subse-
quently published (
http://code.google.com/webstats/2005-12/
classes.html
)
was a list of the most popular class names in those
HTML documents.
More recently, in 2009, the Opera MAMA crawler looked again
at class attributes in 2,148,723 randomly chosen URLs and also
id
s given to elements (which the Google dataset didn't include)
in 1,806,424 URLs. See
Table 1.1
and
Table 1.2
.
