Wrapper

What is Wrapper?

A wrapper is a simple layer that surrounds code or markup to make tasks simpler and results more consistent. In software it often hides technical details, in design it helps organize layouts. Developers often write a wrapper function to take care of typical tasks, decrease the amount of errors, or apply the same rule in many places. In web projects, wrappers might also be used as containers for arranging content across web pages.

Wrapper for Database Access

Different databases use different drivers and rules. A wrapper makes this uniform by exposing a stable interface. Instead of learning each system’s specifics, developers can send calls through the wrapper, which manages connections. A wrapper function makes writing queries less of a headache and keeps tests predictable. In larger systems, they provide a single point for monitoring and keep applications and web sites reliable.

Object-Oriented Programming

In object-oriented programming, a wrapper adapts one object so it can match the interface of the other. This technology allows reuse of libraries and easier integration. The wrapper might add new methods, extend classes, or create containers that bring code elements together without rewriting core parts.

Wrapper for HTML

In html documents, people typically use a div as the wrapper. It groups content, images, or media and applies css rules. By organizing sections with this technology, developers can structure html files, apply css classes, and maintain layouts. Wrappers remain essential in web design, supporting scalable and responsive web pages over time.
