Tailor is a Chrome extension designed to streamline the process of inspecting spacings on websites. By holding the toggle key (Alt or Option) and hovering over elements on a webpage, users can easily view size, margin, and padding highlights, along with pertinent font information displayed in a dedicated panel. This functionality aids developers in assessing layout designs effectively.

In addition to hover inspections, Tailor allows users to click on an element to lock it in place, entering a measuring mode. This feature displays the distance between the locked element and any other element that is hovered over, facilitating precise spacing measurements. As an open-source tool, Tailor is accessible for developers interested in its source code and contributions, ensuring continuous improvement and support for its user community.
