After preview, if you approve the HTML/CSS, you are more than welcome to provide changes that you need done in order for the project to be fully pixel perfect based on your PSD files. You will have 3 rounds of edits (for example: font styling, minor alignment changes, JS effects) and if you require a change in the design that might require extra efforts, we may have to charge an additional fee. A round can be defined as a list of edits that we are going to complete. Once the first round is fully completed, if you need a few more changes you will be able to send a second round and a third round if needed. The programmer will need a detailed list of changes (screenshots if possible) so we can provide a fast and efficient result (this screenshot tool may be helpful: http://awesomescreenshot.com/) After the 3 rounds of edits are finalized you can ask for more changes, but this will be charged separately.
If your project is a CMS: Edits on the CMS have the same flow as the HTML process, but they are only related to functionality (for example: change widgets, use different plugins, the logic of the code) and not HTML/CSS because we will be using the HTML code that you previously approved.
