Can A Figcaption Be Restricted To The Width Of A Responsively Sized Image?


Answer :

Old question, but I came across the same issue and was able to come up with a fairly neat solution, inspired by this.

HTML:

<figure>    <img src="http://www.placehold.it/300x150" alt="" />    <figcaption>Make me as long as you like</figcaption> </figure>​

CSS:

figure {    background-color: #fff;    padding: 5px;    font-size: .875em;    display: table; }  figure img {     display: block;     width: 100%; }  figcaption {     display: table-caption;     caption-side: bottom;     background: #fff;     padding: 0 5px 5px; }​

This ensures the figcaption does not exceed the width of the figure, whilst allowing you to keep max-width on the image. Works in all good browsers and IE8+.

There's a Firefox bug that prevents max-width working within elements that are set to display: table. So, instead of using max-width on the image, setting its width to 100% means this works cross-browser. The figure's width will be whatever the native width of the image is, unless that width is restricted in some other way.


So is it possible to use CSS (2 or 3) to achieve both an image caption wrapped to no wider than the image, and an image no wider than the viewport?

Yes. Just use viewport units on the img - max-width: 100vw; instead of % - max-width: 100%;

DEMO

Just for completeness:

There are 2 other techniques to get the text to wrap to the width of the image:

1) Set display: table-caption; on the figcaption

DEMO

2) Set width: min-content on the figure

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.
