Abstract: A website is opened in a website development tool, and pages of the website are served with a web server. The web server accepts user input arranged to direct interactive execution the web page being served. A design editor is opened while the web pages continue to be served. The design editor presents a digital graph paper image configured to display one or more separately identifiable groups of one or more grid blocks of the digital graph paper image. Each of the separately identifiable groups represents a displayable object included in at least one web page. User input into the design editor is arranged to select a sector of grid blocks and modify a set of characteristics associated with the sector. A build process and a deployment process are executed in real time and the modified web page is served in real time.
