Impact of Browsers on Web Design

Impact of Browsers on Web Design" Please respond to the following:

• Due to the internal style sheets of some browsers, your Website may look different to someone who is using Firefox as opposed to Internet Explorer. Imagine that you are a Web designer. Explain how would you address this problem and eradicate these inconsistencies.
• Imagine that you are Web designer for a company of your choice (travel, bank, pet food, hair salon, high school, college, landscaper, retail store, etc.). Identify the company and describe what you would check to ensure that a Website is compatible with most browsers.

THIS IS  A DISCUSSION QUESTION THAT SHOULD BE NO LONGER THAN 1 PAGE.
