The SCSS allows developers to write CSS in a more structured way. Also, we can create multiple files for CSS while using the SCSS and import the required file in the main SCSS file. In this tutorial, we will see the objective to put ‘_’ before the filename in SCSS. When should we put ‘_’ in front of the filename in SCSS? Whenever we put the -_’ before the filename in the SCSS, the compiler ignores the file while compiling the SCSS. The file becomes partial if the filename starts with the ‘_’ character. For example, we have two ... Read More
What is SASS? The full form of the SASS is Syntactically Awesome Style Sheets. It is a preprocessor or compiler which we can use to compile the SCSS. Now, the question is that what is the SCSS? The SCSS allows developers to write CSS code in a better way as it contains the variables, nested rules, functions, etc., and similar advanced features. For example, we can use variables in SCSS, so we don’t need to write a single value multiple times but can access it using the variable name. Similarly, we can create functions in SCSS and stop ...

In HTML 4, the and tags were included, but in HTML 5, only the tag exists as the tag is removed by developers. Why tag exists but not tag in the HTML 5 The tag was useful to make the font size bigger than the normal fonts. For example, if the default font size in the browser is small, the big tag makes it medium. The tag is used to make a font size smaller than the normal fonts. If the default font size is medium in the browser, the ... Read More
Developers can use JavaScritp or JQuery to manipulate the style of the HTML elements. For that, first, developers need to access the HTML elements using JQuery and then use various methods to set the style for selected HTML elements. Sometimes, we require to manage elements styles using JQuery. For example, when users click the button, we need to change the text's colour, image dimensions, etc. In this case, we can use the JQuery methods below to change the HTML elements' style. Use the CSS() method of JQuery to set styles on selected elements The first method is the css() ... Read More
In SASS, the directive is a special symbol that starts with the ‘@’ character. There are various kinds of directives that are used in the SCSS code, instructing the compiler to process the code in a particular way. In this tutorial, we will learn about the @error and @debug directives used to throw an error or debug the code, respectively. @error directive in SASS The error directive is represented like ‘@error’, and we can use it whenever we require to throw an error. For example, if some condition doesn’t meet, we require to throw an error. Syntax Users ... Read More
We can store and retrieve key-value pairs using two popular data structures in programming: maps and hash maps. They both serve to symbolize a group of components that may be accessed by means of a special key. A collection of key-value pairs is represented using a Java interface called a Map. It is an abstract data type that offers methods for accessing, adding, and removing elements as well as a way to map keys to values. On the other hand, a HashMap is a real-world application of the Map interface. What are Maps? In computer science, a map is a ... Read More
HTML and XHTML are computer languages that are used in the development of web pages. It has simpler syntax that can be understood easily. XHTML is the extension of HTML which also combines the features of XML. It has more strict syntax than HTML. Although XHTML is derived from HTML, there are considerable differences between these two. What is HTML? The full form of HTML is Hypertext Markup language. It was developed by Tim Berners Lee in the year 1993. It is an extended form of standard generalized markup language (SGML). HTML provides the base or skeleton for the web ... Read More
A combinational circuit is one that contains logic gates. Encoders and decoders are such combinational circuits in which one changes the input data into binary code and the other one decodes it to its original input signal. Both encoders and decoders are multiple input and multiple output devices Encoding allows the input signal to function on various systems. For instance, when we search something in the web browser, it is converted into a binary code (encoding) which can be understood by it then search for it and send the results back to the user by converting the binary form into ...

The term “emulator” is coined by IBM in 1963. Emulation allows a system to emulate other system. For instance, emulation can allow a windows program to run on a mac computer and vice versa. Virtualization is a software program that can be used to divide the physical system into multiple components. These components work independent of the others. A single system is broken into several virtual machines so that each part can be assigned with a specific task. What is Emulation? Emulation is a process in which one system behaves like another system. It allows one computer system to ... Read More
Parasites and parasitoids are two different types of organisms that rely on other organisms for survival. Both are common in nature and have a significant impact on their hosts. However, there is a crucial difference between the two that sets them apart. In this essay, we will explore the differences between parasites and parasitoids in detail. What are Parasites? The term "parasite" comes from the Greek words para, which means "alongside, " and sitos, which means "meal"; "parasitos" means "eating at another person's table." A parasite is another organism which receives nourishment from another organism, termed the host. Parasites may ... Read More
