Needs to be done in 48 hours of placing the bid so bid ONLY IF you can work on it immediately. design requirements:- "These images should be displayed on the page as a set of thumbnails; clicking on a thumbnail should display a full-sized image to the user." "Full-size photos should be able to be closed, and the user should be returned to the thumbnail gallery." Other IMPORTANT Requirements:- "Starting next month, we'll be partnering with a shelter that has 2000 pets available for adoption. We need this page to be able to handle that many listings." "Most people find out about us from internet searches. We need this page to appear towards the top of search results." Keep the following points in mind:- - **Fidelity -** the page needs to do well and do what the design calls for - **Robustness -** the page needs to work across modern web browsers on desktop and mobile - **Maintainability -** the project should be written cleanly, organized clearly and documented well - **Performance -** the page built to load fast and rank well in search engines
