In 2014, Google announced Material Design or material design, which is a visual language that helps unite its Web and Android interfaces. Google has been updating its G Suite apps since then.
The new Gmail, for example, was introduced in April and is now changing a small and crucial tool that you use all the time: the Google login page.
Starting June 14, you will notice a new Google logo, a delineation around the text field and a centered alignment of all the elements on the screen, Google said in a G Suite blog.
So if you notice the change next week, do not be scared. It is Google’s attempt to “express its brand and style through elements such as color, shape, typography and iconography”.
