The big list of fixed stuff in IE7

The IE7 blog has a new post of items that have been fixed in the upcoming release of IE7. While not on the list, the problem I found with alpha transparent png sprites has been fixed for the final release.

Take a look at the list and think of it as new tools to use.

Bugs we fixed

All bugs on positioniseverything.net except the “escaping floats” bug (which is planned for the future)

  • Peekaboo Bug
  • Internet Explorer and Expanding Box Problem
  • Quirky Percentages

  • Doubled Float-Margin bug
  • Duplicate Indent bug
  • Three pixel text jog
  • Creeping Text bug
  • Missing First letter bug
  • Phantom box bug

Details on some of the other bugs (from sources other than the positioniseverything.net list) that we fixed:

  • Overflow now works correctly! (That means boxes do not automatically grow any more.)
  • Parser bugs: * html, _property and /**/ comment bug
  • Select control: CSS style-able and not always on top
  • Auto-sizing of absolute positioned element with width:auto and right & left (great for 3 column layouts)
  • Addressed many relative positioning issues
  • Addressed many absolute positioned issues
  • % calculations for height/width for abs positioned elements http://channel9.msdn.com/ShowPost.aspx?PostID=191182
  • <?xml> prolog no longer causes quirks mode
  • HTML element truly independent of the Body (now gets its own width, height etc.)
  • 1 px dotted borders no longer render as dashed
  • Bottom margin bug on hover does not collapse margins
  • Several negative margin issues fixed
  • Recalc issues including relative positioning and/or negative margins are fixed now
  • CLSID attribute of <object> tag no longer limited to 128 characters
  • :first-letter whitespace bug described in http://blogs.msdn.com/ie/archive/2005/09/02/460115.aspx fixed
  • Descendant selector now works properly for grand children when combined with other selectors
  • First-line and first-letter now applies when there is no space between word :first-line and opening brace {
  • Pseudo-classes now are working as expected if selector is excluded
  • The :link selector works now for anchor tag with href set to bookmark
  • Addressed !important issues
  • PositionIsEverything piefecta-rigid.htm now works
  • List-item whitespace bug fixed
  • Fixed Absolutely Buggy II
  • Absolute positioned elements now use always correct containing block for positioning and size information
  • Nested block elements now respect all overflow declarations (hidden, scroll, etc)
  • Fixed the opposing offset problem (absolute positioned element whit all four top, bottom left and right are present)
  • <a> tags nested within LI elements will no longer add extra bottom margin when hover occurs
  • We no longer lose the image aspect ratio on refresh
  • Cleaned up our ident parsing according to CSS2.1 rules
  • Fixed parsing bugs for multi- class selectors and class selectors that are combined with id selectors
  • And many more

We also extended our existing implementations to comply with W3C specifications:

  • Enable :hover on all elements not just on <a>
  • Background-attachment: fixed works on all elements – so Eric Meyer’s complexspiral demo works
  • Improved <object> fallback

Finally, we added new features from CSS2.1:

  • Min/max width/height support (also for images, which did not work in IE7b2)
  • Transparent borders
  • Fixed positioning support
  • Selectors: first-child, adjacent, attribute, child
    • A couple of CSS 3 attribute selectors: prefix, suffix and substring since we were working already in the code base (also the general sibling selector)
  • Alpha channel PNG support (Not a CSS feature but too important for designers to not call it out J)

IE Blog

IE7 is still not as good as Firefox, Opera, or Safari. However, Microsoft is planning an aggressive updating campaign and hopefully it won’t be long before we can count on our average user’s browser supporting advanced CSS styles. It’s time to stop complaining about IE6 and begin planning how you will use these new tools.

  1. IE7 still has the duplicate character bug. I am not sure what is triggering it but I was able to hack together a fix. If I simply add some spaces (on occasion I had to explicitly define the space with &nbsp ; ) the IE7 seems to duplicate the space instead of the characters; this could cause formatting issues which will have to be worked around but it is much better than extra characters being displayed.
