Default style feature is not suitable for default bootstrap stander theme.

[AhmedBHameed]

The default them is materialize theme which is not suitable with the stander bootstrap them.
either adding an external file for css because the style is attached at the end of the head so there is no ability to modify it!!!

Or at least you can add a stander template as a function then any one can modify the style to it's shape.
Thanks.
