The px belongs to the absolute category of length units whereas the em and %(percentage) refer to the relative class of sizing units. The value of px is fixed over the HTML document but the em and %(percentage) depend on the unit used by the parent element. The em majorly manipulates the font size of the HTML elements, and the (%)percentage unit primarily refers to changing the height/width of an HTML element (according to the parent element). In this article, you would have learned the basics of various units such as px, em, and percentage. For better understanding, we have demonstrated an example that better clarifies the difference between all these units.

HTML elements can be styled with respect to their attribute names or attribute values. There are a total of seven CSS attribute selectors which are: [attribute] selector, [attribute= “value”], [attribute ~=“value”] selector, [attribute |=“value”] selector, [attribute ^=“value”] selector, [attribute $=“value] selector, and [attribute *=“value”] selector. These all selectors serve a different purpose which we are discussed in detail in this post along with relevant examples.

In JavaScript, the Constructor method is invoked when you create an instance of a class. Constructors in JavaScript can be of different types, such as the Built-in JavaScript Constructors, the Custom Constructor function, and the Constructor method of a user-defined class. The Constructor method is further divided into Default and Parameterized Constructors. Depending upon requirements, you can use these constructors for creating and initializing a class's object or instance.

In Bash programming, variables play a vital part in transforming the script to a modern standard. Variables are named symbols representing a string or numeric value. When creating a Bash variable, it must have a value. However, we can set a default value if the variable is not set (or null). This article discusses how to assign a default value if the variable is unset.

expires, max-age, path, and domain are the attributes of cookies in JavaScript. The expires and max-age attributes are utilized for setting the expiration date and the lifetime of cookies. In contrast, the combination of domain and path attributes assist in specifying the valid domain and scope where the cookies are available. This write-up explained the attributes of Cookies in JavaScript with the help of suitable examples.

Asynchronous Iterators and Asynchronous Generators are utilized to iterate over the data, provided after a certain amount of time. The Asynchronous Iterators execute the Symbol.asyncIterator() method to return an iterator, whereas the Asynchronous Generators return a special type of Generator by itself, which can be used wherever the iteration is required.

ArrayLists are the implementation of List Interface where elements can be added and removed from the list dynamically while LinkedList is a linear data structure that is formed by a chain of nodes where each node contains the value and a link to the location of the next node in the chain. Considering the similarities and differences of both these lists it is concluded that ArrayLists has the upper hand in storing and accessing the data while LinkedList provides better manipulation of data.

The ArrayList class is utilized to create a dynamic/variable length data structure in Java. To work with Arraylist firstly we have to import the ArrayList class of java.util package into our project. The ArrayList class provides a wide range of methods to perform different functionalities e.g. add() method is used to add items in a list, remove() method is used to delete an item from a list, the sort() method is used to sort the ArrayList in numeric or alphabetic order.

Abstraction in JavaScript can be implemented with the help of Abstract Classes and Abstract Methods. In JavaScript, an Abstract class must contain at least one or more declared Abstract methods, whereas its definition can be added in its sub-classes. Abstraction in JavaScript hides the details of the underlying system, which can be complex and difficult to comprehend.

Every graph must have a path from one node to another node. A spanning tree is also an undirected connected graph where all the nodes of the graph are present with minimum edges. If a spanning tree doesn't have all the nodes of the graph, then we cannot say that it is a spanning tree. The spanning tree also does not have a cycle. Kruskal’s minimum spanning tree is discussed in this article.

Using Symbol() global function, you can create a JavaScript symbol primitive type that contains a unique value, whereas the Symbol.for() method enables you to create a symbol that can be shared globally. JavaScript symbol primitive type is mostly used to define an object's hidden properties. This write-up explained JavaScript Symbol Primitive Type with the help of suitable examples.

The creation of an object for the corresponding primitive type, whenever a primitive value is read in a program, is known as the primitive Wrapper type. JavaScript offers primitive wrapper types for the string, number, boolean, bigint, and symbol data types, making it easier to use these primitive values. The primitive wrapper types are also called automatically created primitive wrapper objects as they are automatically created when the JavaScript engine reads any primitive value, and these objects get immediately deleted after invoking the specified method or property.

To utilize the functionalities of HashMap in java, first import the HashMap class into your project and then create the object of that class. The HashMap class offers numerous methods to perform different functionalities e.g. put() and remove(), methods are used to insert and delete the entries of HashMap.

The C language came up with many functions to perform many things. Fputs function within the C code is used to write some text or string data within a file. One of its parameters will be a string or pointer to a string to be saved, and the other will be a file descriptor pointing towards the file. Fputs in C is discussed in this article.

The size of a database comprises tables, schemas, functions, and triggers. The content of databases’ tables can increase exponentially, which directly increases the size of the database. So, this change in size should be monitored by the admin on a regular basis so that the process must not be affected due to memory issues. This article discusses how to find the size of a database in PostgreSQL.
