Newbie Help On Basic App Login Button


<?= Html::submitButton('Login', ['class' => 'btn btn-primary', 'name' => 'login-button']) ?>

I would like to understand

'class' => 'btn btn-primary'

. btn is a class which is is present in the css file. but where is btn-primary. Are there any other class combinations like the above available in the basic app.

Could some one point me to the direction of a good tutorial which will explain me the basic app in detail.



btn-primary is also a css style for bootstrap.

You can see a list of style options on bootstraps website.

great, got it.

Many Thanks :)
