Controlling The Amount Of Space In Justify-content: Space-between


Answer :

The justify-content property uses the available space on the line to position flex items.



With justify-content: space-between, all available space is placed between the first and last items, pushing both items to opposite edges of the container.

I was wondering how to justify how much space is allowed in justify-content: space-between for flexbox.




With space-between in row-direction, you would have to control the width of the flex container. So if you want there to be less space between flex items, then you would need to shorten the width of the container.



Or you could use justify-content: space-around.



However, these solutions are suboptimal.



The right way to go about this would be to use margins.

Currently, my items are spaced but they have way too much space between them I want just a little space between them so they can settle somewhere in the middle in a row.




Use justify-content: center then use margins to space them apart.



I find myself adding right margin to all the boxes (in this case three)



.three {
    margin-right: 2%
}


and then getting rid of it so the last box aligns right



.three:nth-child(3) {
    margin-right: 0%;
}


but every time I do this I think "there has to be a better way, something baked into flex-box...this works but it seems like a workaround?



The approach with using margins is not a universal solution if you want space-between, because it would set a margin on all the flex-elements, also on the first and last elements on a line or column. Using :first-child / :last-child/ :nth-child() selector doesn't help when flex-wrap: wrap is set, because you can never tell which elements will be first and last on a wrapped line or column.



A selector like :wrapped would be helpful, but sadly it doesn't exist.



So my conclusion is that when you really want to unleash the flexibility and responsiveness of the flexbox, you can't control the margins… Missed opportunity of the spec I'd say.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
