You can use all Unicode characters and the escape characters  n and  t  An example    x000D   x000D  document getElementById  test   onclick   function     x000D    alert  x000D       This is an alert with basic formatting n n   x000D          t    list item 1 n   x000D          t    list item 2 n   x000D          t    list item 3 n n   x000D                                 n n   x000D         Simple table n n   x000D         Char t  Result n   x000D           n t  line break n   x000D           t t  tab space  x000D       x000D    x000D   lt  DOCTYPE html gt  x000D   lt title gt Alert formatting lt  title gt  x000D   lt meta charset utf-8 gt  x000D   lt button id test gt Click lt  button gt  x000D   x000D   x000D    Result in Firefox     You get the same look in almost all browsers

alert    doesn t support HTML  but you have some alternatives to format your message   You can use Unicode characters as others stated  or you can make use of the ES6 Template literals  For example        catch function  error      const alertMessage    Error retrieving resource  Please make sure          the resource server is accessible         you re logged in      Error    error      window alert alertMessage        Output    As you can see  it maintains the line breaks and spaces that we included in the variable  with no extra characters

This is not possible   Instead  you should create a fake window in Javascript  using something like jQuery UI Dialog

No  you can use only some escape sequences -  n for example  maybe only this one
