Hello, The goal of this project is to take 1 php/javascript web page and optimize it, fix problems, and add features. This project has 2 sections: A. Optimize page B. Fix problems ------------------------------------- This is the page: [login to view URL] ------------------------------------- A. OPTIMIZE PAGE: REDUCE PAGE SIZE / INCREASE SPEED ------------------------------------------------ 1. The first thing to do in this project is to combine images to use sprites instead of individual images. Have in as few images as possible, combine together. Of course this will have to be done with the original .psd files, so quality is not degraded. 2. Combine css code styles so there is no redundancy or waste. Currently, the css file is a mess and it can be faster when redundancy is removed. This is a manual and delicate process of going through and removing css that doesn\'t affect the page, then testing the page in browsers to ensure you didn\'t lose any functionality. Please do not minify anything until the very end with a separate copy, so we don\'t lose the ability to read it. 3. I would like to get rid of jquery and only have custom lightweight javascript for the required features. The only feature dependent on jquery I\'m aware of is the sticky header, and it\'s possible it can be made so its not jquery dependent. At minimum jquery should be customized and have unnecessary features removed ([login to view URL] ) My #1 goal is to have the page load under 1 second in Pingdom: [login to view URL] and to get a 100% PageSpeed grade and 100% Yslow grade in GTMetrix. It shall be extremely light and efficient. REQUIREMENTS: 1. Page loads under 1 second (using Pingdom and GTmetrix to verify) 2. Total page size under 300K 3. Total server requests under 25 4. 100% PageSpeed grade and 100% Yslow grade (using GTMetrix) The reason this is so important is that it\'s on a very high traffic site (millions of visitors) with pageloads in bursts of 50 times a second in peak times, plus popular on mobile with low bandwidth devices, so it must be very very very fast and lightweight code. I cannot emphasize enough how important this is. This is not a project where a few things are quickly optimized which is \'good enough\' then move on. Rather, the entire purpose of this project is to optimize in a meticulous, utmost level of attention to detail until it is 100% optimized in every possible way. If you don\'t like this kind of detailed work, then please don\'t bid on this one. The hired person must be really good at doing this already and enjoy it for this project to be successful. Currently, the page is inefficient and loads in 3 seconds, which is too slow. I want to keep the features and design but reduce the size to the above specs and this will be done in a few ways: Minifying css, html, and javascript should be be done absolutely last and as a separate copy, so we don\'t make the code impossible to read/edit in future. At the very end after all code is locked down, then a separate copy can be made that is minified (keeping original unminified versions). I also have another version of the page that a different coder made- some of it can be leveraged, like some sprites, but not all. Sprites will need to be done from original .psd layered file to preserve quality. B. PROBLEMS TO FIX: ------------------------------------------------ 7 of them. This page for some reason limits characters to 4000, but this project has more detail. Please see this page for the rest of this project (IMPORTANT): [login to view URL]
