Final answer:
When using inspect element, you can temporarily modify the HTML, CSS, and JavaScript of a webpage in the browser, but these changes do not affect the actual webpage. It is useful for testing and experimenting before implementing permanent changes.
Step-by-step explanation:
When using the inspect element in web development, you can view and modify the HTML, CSS, and JavaScript of a webpage in the browser. However, any changes you make using the inspect element are only temporary and do not affect the actual webpage. They are local to your browser and will be lost upon refreshing the page or closing the browser.
For example, if you find a button on a webpage, you can change its appearance or behavior using the inspect element. This is useful for testing different design options or experimenting with code changes before implementing them permanently.
It's important to note that while using the inspect element can help you understand how a webpage is built and make temporary changes for testing purposes, it does not allow you to change the actual webpage itself.
