Quotation marks to wrap an element in HTML

In HTML, quotation marks can be used to wrap an element, providing visual emphasis and indicating that the enclosed content represents a quotation.  This styling technique enhances the presentation of quoted text on web pages. Setting default quotation marks: To set quotation marks to wrap an element in HTML, you can use the `quotes` CSS property along with the `content` property to specify the quotation marks to be used (the below example uses the default quotes value, so it is not mentioned as can be seen). Here's how it can be achieved: /* Define the quotation marks */ .q:before { content: open-quote; } .q:after { content: close-quote; } In this CSS: - `open-quote` represents the opening quotation mark. - `close-quote` represents the closing quotation mark. Now, you can apply the `.q` class to elements where you want to set quotation marks: <p class="q">This is a quoted text.</p> This will render as: “ This is a quoted...

Using insertAdjacentHTML instead of innerHTML to avoid XSS attacks

SOLID principles for software development

SOLID principles  are five design guidelines for writing clean, maintainable, and scalable object-oriented software. The acronym stands for: S - Single Responsibility Principle (SRP) : A class should have one and only one reason to change. O - Open/Closed Principle (OCP) : Software entities should be open for extension but closed for modification. L - Liskov Substitution Principle (LSP) : Subtypes must be substitutable for their base types. I - Interface Segregation Principle (ISP) : No client should be forced to depend on methods it does not use. D - Dependency Inversion Principle (DIP) : Depend on abstractions, not on concrete implementations. 1. Single Responsibility Principle (SRP) Definition : A class should only have one responsibility or reason to change. Why? Simplifies maintenance and avoids unintended side effects when modifying code. Example : Bad : A class managing both user authentication and database operations. Good : Separate classes...
