 # Guidelines
 
 ## Design
 
-- Dialogs have a max width of 560px. Alert and confirmation dialogs got a fixed width of 320px. If you need more width, consider a dedicated page instead.
-- The close X-icon is on the top left, on all screen sizes. Except for alert and confirmation dialogs, they only have buttons and no X-icon. This is different compared to the Material guideliness.
+- Dialogs have a max width of 560px. Alert and confirmation dialogs have a fixed width of 320px. If you need more width, consider a dedicated page instead.
+- The close X-icon is on the top left, on all screen sizes. Except for alert and confirmation dialogs, they only have buttons and no X-icon. This is different compared to the Material guidelines.
 - Dialogs can't be closed with ESC or clicked outside of the dialog when there is a form that the user needs to fill out. Instead it will animate "no" by a little shake.
 - Extra icon buttons are on the top right, for example help, settings and expand dialog. More than 2 icon buttons, they will be in an overflow menu.
 - The submit button is grouped with a cancel button at the bottom right, on all screen sizes. Fullscreen mobile dialogs have them sticky at the bottom.

 - A best practice is to always use a title, even if it is optional by Material guidelines.
 - People mainly read the title and a button. Put the most important information in those two.
-- Try to avoid user generated content in the title, this could make the title unreadable long.
+- Try to avoid user generated content in the title, this could make the title unreadably long.
 - If users become unsure, they read the description. Make sure this explains what will happen.
 - Strive for minimalism.
