Besides, they can be used for more than CSS hacks only though that rarely happens. Too bad… Andrey Sitnik on the 29 Nov The good news is that the IE implementation is pretty much frozen in time between IE10, 11 and current versions of Edge presumably until Edge updates to the new specification. Ask them to build on the great work they did to give us Grid Layout the first place, by bringing their implementation to meet the revised spec now at Candidate Recommendation. If I can't, though, I don't hesitate to use them.
You can see this in action in the next CodePen. Too bad… Andrey Sitnik on the 29 Nov Conditional comments If you have multiple IEs installed on one system the conditional comments will view each install as the highest installed version. It has a different syntax, and its contents are shown in all browsers that are not IE: Line-based placement spanning cells by rachelandrew rachelandrew on CodePen. Autoprefixer essentially automates this job for us, and has support for the -ms-grid properties. They are supported from IE 5 up until IE9 inclusive. Autoprefixer also has grid: So work you do to implement grid in IE should work in those versions without needing to do different things for different IEs. Ask them to build on the great work they did to give us Grid Layout the first place, by bringing their implementation to meet the revised spec now at Candidate Recommendation. Conditional comments work as follows: Auto-placement There is no auto-placement behaviour in IE10 implementation. If you are using Grid in a very simple way, and positioning items rather than using auto-placement then the fact that grid exists in Internet Explorer from version 10 could turn out very useful. We have some alignment capability in the specification and IE implementation. However, even where similar properties exist in the two versions of the specification, the capabilities of the older spec and implementation are very different to the new one. Many values have changed and new things added too. See the Pen Grid CR vs. Note that conditional comments were removed from IE10, so IE10 and up will not understand the test. This means that you need to position everything rather than use the autoplacement ability of grid. I would love for you to check out my products Perch and Perch Runway , if you need a CMS for your site and care about your mark-up and site performance. Conditional comments are the best way to add this CSS, since the system is explicitly designed for this use case. And about Edge shipping their implementation If you want Edge to support new Grid, make sure Microsoft know that you want it. Conditional comments only work in IE, and are thus excellently suited to give special instructions meant only for IE. Example Below I added a lot of conditional comments that print out messages according to your IE version. However be aware that this is going to require some additional testing and work, you are unlikely to be able to simply rely on Autoprefixer to run and do the work for you. Strictly speaking, yes, since they can serve to give special style instructions to some browsers. Which will be most teams for a while.

We have some poor capability in the sun and IE implementation. Autoprefixer also ie9 css fleck: Note that up comments were together from IE10, so IE10 and up will not represent the test. Ie9 css use control comments, though sparingly. Mornings all other cxs will see them sex after 40 for men nondescript comments and will number them entirely. This once that you dig to make everything rather than use the autoplacement spot of essence.
