Esse padrão é apresentado usando um layout flexível simples demonstrando como uma linha de CSS pode nos fornecer nossa navegação. Os separadores são adicionados usando o conteúdo gerado por CSS. Você pode alterá-las para qualquer separador que desejar.

Notes
Notes Internet Explorer 11 ignores uses of calc() in the flex-basis part of the flex syntax. This can be worked around by using the longhand properties instead of the shorthand. See Flexbug #8 for more info.
Notes Internet Explorer 11 considers a unitless value in the flex-basis part to be syntactically invalid (and will thus be ignored). A workaround is to always include a unit in the flex-basis part of the flex shorthand value. See Flexbug #4 for more info.
