CSS

 

Cascading Style Sheet (CSS) is to to format the webpage. It describes how the HTML elements are displayed in a webpage. Its flexibility and cascading nature make it a powerful tool for creating visually appealing and responsive user interfaces.

Linking CSS to HTML:

  • Inline: <div style="property: value;">Content</div>
  • Internal: <style> /* CSS code */ </style> within the HTML file.
  • External: Link an external CSS file using <link rel="stylesheet" type="text/css" href="styles.css">

Key Concepts

  • Selectors

  • Selectors target HTML elements to apply styling.
  • element, universal selector (*), id name(#<id name>), class name(.<class name>)
  • Examples: div, .class, #id, :hover.

  • Properties

  • Properties define the style to be applied.
  • Examples: color, font-size, margin.

  • Values

  • Values specify the setting for a property.
  • Examples: #0000FF (color), 16px (font size), 10px 20px (margin).

  • Box Model

  • The box model describes the layout of elements, including content, padding, border, and margin.

  • Selectors and Combinators

  • CSS allows complex selections using combinators like space, >, +, and ~.
SASS also known as Syntactically Awesome Style Sheets, is a preprocessor scripting language that is interpreted or compiled into CSS. SASS offers features such as variables, mixins, and nested rules, which can help streamline the process of writing and maintaining CSS code.

Transform values with a stream

The goal is to transform an array of numbers into a comma-delimited string using functional programming. The code snippet you provided has a minor issue: String.join(",", strings[0]) is incorrect because it tries to join a single element ( strings[0] ) rather than all elements in the strings array. Here's the corrected code for the transformValues method: import java.util.Arrays; class Answer {     // Change these boolean values to control whether you see      // the expected answer and/or hints.     static boolean showExpectedResult = true;     static boolean showHints = true;     // Transform an array of numbers into a comma-delimited list     // using functional programming.     static String transformValues(int[] numbers) {         // Convert the int array to a stream of integers         // Map each integer to its String representation         // ...

Collections Framework

 The Java Collections Framework provides a comprehensive set of interfaces, implementations, and algorithms to work with collections of objects in Java. It offers a unified architecture for representing and manipulating collections, making it easier to work with data structures in Java programs. The Collections Framework is a fundamental part of Java programming and is widely used in various applications ranging from simple data manipulation tasks to complex algorithms and data processing pipelines.  Key components of the Collections Framework: Interfaces Collection : The root interface of the Collections Framework hierarchy. Represents a group of objects, known as elements. Subinterfaces include List , Set , and Queue . List : Represents an ordered collection of elements where duplicate elements are allowed. Allows elements to be accessed and inserted by index. Implementations include ArrayList , LinkedList , and Vector . Set : Represents a collection of unique elements ...
