Question

Why does Eric Meyer have not advisable, presentational, deprecated, and non-semantic tags in his css reset? (I.e. applet, iframe, big, s, small, strike.)

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, font, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td 
{
  margin: 0;
  padding: 0;
  border: 0;
  outline: 0;
  font-weight: inherit;
  font-style: inherit;
  font-size: 100%;
  font-family: inherit;
  vertical-align: baseline;
}

Answer 1

Because people still use them, unfortunately. There’s nothing invalid about referencing deprecated elements in your stylesheet. It’s invalid to actually use them in your markup. Meyer’s reset is to fix the way your elements render, not to fix which elements you choose to use to begin with.
