css bootstrap 3 or 4 ?

[paskuale75]

What version of bootstrap supported ?

[simialbi]

It's bootstrap 3 a.t.m.

[paskuale75]

there's a way to improve the style ?

It's because JqueryUI CSS overrides styles:
inserting following in the config

'components' => [
    'assetManager' => [
        'bundles' => [
            'yii\jui\JuiAsset' => [
                'css' => []
            ]
        ]
    ]
]

should do the trick
