CSS Position:fixed Inside A Positioned Element


Answer :

You can use the position:fixed;, but without set left and top. Then you will push it to the right using margin-left, to position it in the right position you wish.

The current selected solution appears to have misunderstood the problem.



The trick is to neither use absolute nor fixed positioning. Instead, have the close button outside of the div with its position set to relative and a left float so that it is immediately right of the div. Next, set a negative left margin and a positive z index so that it appears above the div.



Here's an example:



#close
    {
        position: relative;
        float: left;
        margin-top: 50vh;
        margin-left: -100px;
        z-index: 2;
    }

#dialog
    {
        height: 100vh;
        width: 100vw;
        position: relative;
        overflow: scroll;
        float: left;
    }

<body> 
    <div id="dialog">
    ****
    </div>

    <div id="close"> </div>
</body>


Position:fixed gives an absolute position regarding the BROWSER window. so of course it goes there.



While position:absolute refers to the parent element, so if you place your <div> button inside the <div> of the container, it should position where you meant it to be.
Something like



EDIT: thanks to @Sotiris, who has a point, solution can be achieved using a position:fixed and a margin-left. Like this: http://jsfiddle.net/NeK4k/

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.
