More about the parser at SO: How does the Windows Command Interpreter (CMD.After the HDXPRT 2014 release last week, we discovered a new issue. The caret variant also works when mu has content before the line is executed. In your case, call echo %mu% would also work, but only when mu is always empty. To echo the variable content, I use call echo %^mu%, as percent expansion will expand it when the line is parsed, before any of the commands are executed.īut the call command will be executed later, and it restarts the parser, which, when used at the command line, uses different expansion rules than the batch parser: an empty variable (in this case, %^mu%, in the first time) stays unchanged in the line but, in the next parser phase, the ^ caret will be removed. So the content will be no quotes, as only the content to the last quote is used the rest will be dropped. In the second test, it uses the extended syntax of the SET command. In the first test, the quotes will be part of the test1 variable, as well as all characters after the last quote.
You can do it in the same line, but I would recommend to use a batch file like preHook.bat.Īs one liner set "mu=hello, world!" & call echo %^mu%Īt first you can see that the quotes are different than yours. I haven't run into any negative effects from that (though I'd be glad to hear if others do). If you are floating left, add a several pixel negative margin on the right. The other solution that I've found when 'overflow' just wont cut it is to add a small negative margin to the last element in a row. Nicole Sullivan has an interesting solution based on using 'overflow: hidden ' on your last column rather than a float/width combination. There are various solutions depending on your situation.
At that point IE decides the second box can't fit and drops it below.
Rounding up, your container width at 721px will include one box at 505px and another at 217px for a total of 722px - more than 100%. Most browsers figure out a rounding solution for you that doesn't break the layout. 721 is arbitrary, but using percentages you'll run into arbitrary numbers. When you are designing with percentages there will be times that the math doesn't result in full pixels (70% of 721px is 504.7px).
