+## The Acid Tests
+
+This directory contains copies of Acid2 and Acid3, based on the
+copies hosted at [acidtests.org](http://www.acidtests.org) after they
+had ceased being maintained (per the note on that page).
+
+Note these are not maintained here for the sake of providing any
+useful guide of interoperability or standards compliance, but rather
+for browser vendors' convenience. It would be inappropriate,
+therefore, to use them as part of a certification process.
+
+Acid1 can be found at `css/CSS2/css1/c5526c-display-000.xht`, as it
+always formed part of the CSS1 testsuite.
+
+The tests themselves (i.e., those at `/` of their respective
+subdomains at `acidtests.org`) are in files named test.html in their
+respective directories.

+  /* The line-height for the .bucket div is worked out as follows:
+   *
+   * The div.bucket element has a line box with a few
+   * inline-blocks. Each inline-block consists of:
+   *
+   *     2.0em vertical-align from baseline to bottom of inline-block
+   *     1px bottom border
+   *     1.0em bottom padding
+   *     1.0em top padding
+   *     1px top border
+   *
+   * The biggest inline-block has font-size: 40px.
+   *
+   * Thus the distance from the baseline to the top of the biggest
+   * inline-block is (2em+1em+1em)*2em*20px+2px = 162px.
+   *
+   * The line box itself has no other contents, and its strut has zero
+   * height and there is no half-leading, so the height of the
+   * div.bucket is 162px.
+   *
+   * (Why use line-height:0 and font-size:0? Well:
+   *
+   * The div.bucket line box would have a height that is the maximum
+   * of the following two sums:
+   *
+   *  1: half-leading + font descent at 1em + font ascent at 1em + half-leading
+   *  2: half-leading + font descent at 1em + 162px
+   *
+   * Now the half-leading is (line-height - (font-ascent + font-descent))/2, so that is really:
+   *
+   *  1: (line-height - (font-ascent + font-descent))/2 + font descent + font ascent + (line-height - (font-ascent + font-descent))/2
+   *  2: (line-height - (font-ascent + font-descent))/2 + font descent + 162px
+   *
+   * Which simplify to:
+   *
+   *  1: line-height
+   *  2: line-height/2 + (font descent - font-ascent)/2 + 162px
+   *
+   * So if the following expression is true:
+   *
+   *    line-height > line-height/2 + (font descent - font-ascent)/2 + 162px
+   *
+   * That is, if this is true:
+   *
+   *    line-height > font descent - font-ascent + 324px
+   *
+   * ...then the line-height matters, otherwise the font does. Note
+   * that font descent - font-ascent will be in the region of
+   * 10px-30px (with Ahem, exactly 12px). However, if we make the
+   * line-height big, then the _positioning_ of the inline-blocks will
+   * depend on the font descent, since that is what will decide the
+   * distance from the bottom of the line box to the baseline of the
+   * block (since the baseline is set by the strut).
+   *
+   * However, in Acid2 a dependency on the font metrics was introduced
+   * and this caused all kinds of problems. And we can't require Ahem
+   * in the Acid tests, since it's unlikely most people will have it
+   * installed.
+   *
+   * What we want is for the font to not matter, and the baseline to
+   * be as high as possible. We can do that by saying that the font
+   * and the line-height are zero.
+   *
+   * One word of warning. If your browser has a minimum font size feature
+   * that forces font sizes up even when there is no text, you will need
+   * to disable it before running this test.

+//      // on the <set> element. The animation is a simple animation
+//      // that sets the value of the width attribute to 0. The duration
+//      // of the animation is 'indefinite' which means that the value
+//      // will stay 0 indefinitely. The target of the animation is the
+//      // 'width' attribute of the <rect> element that is the parent of
+//      // the <set> element. When 'width' is 0 the rect is not rendered
+//      // according to the spec[7].
+//      //
+//      // Some properties of the SVGAnimatedLength[2] and SVGLength[8]
+//      // are also inspected. Before the animation starts both baseVal
+//      // and animVal contain the same values[2]. Then the animation is
