The & operator is the parent selector. When used in or as a selector, it is replaced with the full parent selectors (entire sequence of selectors right upto to the topmost level of a nested block) in the final CSS output. It is useful when creating nested rules that require using the parent sel...

Less allows the usage of the parent selector (&) anywhere in a complex selector and thus allows changing styles when the current element is within another element which gives it a different context: For example, in the below code the parent selector is placed at the end and thus it actually be...

In Less you can write much more simple CSS rules and also keep them well formatted, so instead of writing this code: CSS .item { border: 1px solid; padding: 4px; } .item .content, .item .image { float: left; } .item .content { font-size: 12px; } .item .image { width: 300px; }...

The @import statement allows you to insert CSS/Less code from another file into your own CSS/Less file. .foo { background: #900; } @import "my-other-css-file.css"; @import "my-other-less-file.less";

If multiple signatures are to be integrated into a PDF, this is done by means of incremental PDF updates (explicitly not by adding multiple SignerInfo structures to a single integrated CMS signature container!): The cryptographic verification of these signatures merely guarantees that the byte ra...

Quick start A rule describes when and how certain files (rule's targets) are created. It can also serve to update a target file if any of the files required for its creation (target's prerequisites) are newer than the target. Rules follow the syntax below: (Note that commands following a rule are ...

A while loop is used to execute a piece of code while a condition is true. The while loop is to be used when a block of code is to be executed a variable number of times.

Here is a generic ViewHolder class that you can use with any DataBinding layout. Here an instance of particular ViewDataBinding class is created using the inflated View object and DataBindingUtil utility class. import android.databinding.DataBindingUtil; import android.support.v7.widget.RecyclerVi...

Unlike for and while loops, do-while loops check the truth of the condition at the end of the loop, which means the do block will execute once, and then check the condition of the while at the bottom of the block. Meaning that a do-while loop will always run at least once. For example this do-while...

A use case that comes across frequently, is creating a String from a stream, where the stream-items are separated by a certain character. The Collectors.joining() method can be used for this, like in the following example: Stream<String> fruitStream = Stream.of("apple", "banana...

A collection can be created by using the CreateDocumentCollectionAsync method of the DocumentClient class. A collection is a container of JSON documents and associated JavaScript application logic. async Task CreateCollection(DocumentClient client) { var databaseName = "<your database...
