Let me clarify on what button we use. 

The problem is not with the kendo button but with the bootstrap button combined with Kendo theme SASS.

    <button class="btn btn-primary">Sign in</button>
    <button class="btn btn-secondary">Password</button>


When you use the default bootstrap button (style) when combined with kendo, the kendo theme bundle overrides bootstrap styling. Applying a shadow on the btn class of bootstrap. 

As previously stated, on the theme builder, when you scroll down to the button section where the default bootstrap button is used without the kendoButton attribute and with the class="btn ..." styling, there is a strange shadow applied.

Because kendo does not support a success, danger etc.. type button, we still use the bootstrap button.

 

Kind regards,

Maikel

Hello,

Thank you for the provided additional details about this case.

If I understand correctly, the initially provided image was taken from our ThemeBuilder application. I checked it, but there is no such styling issue (Bootstrap theme used ):

Based on the provided information - 'If we use precompiled, there is no issue. But to minimize the size of styling, we only load that is needed.'  it seems that the issue is caused when importing the style files for the components in use (following this approach).

I created an example, where I load just the button styles

but the buttons are again rendered without the discussed styling mismatch

I am attaching the project, used for testing purposes.

Please let me know, am I missing something.

Regards,
Martin

As requested:

The image is taken directly from: Progress Sass Theme Builder (telerik.com) as an example. The same issue resides in our application

To reproduce:
1. Load kendo through sass
2. Load Bootstrap through sass
3. Compile sass

The precompiled doesn't have this issue because it does not conflict with the bootstrap variables.
We don't have any custom styling applied on neither Kendo nor Bootstrap. If we use precompiled, there is no issue. But to minimize the size of styling, we only load that is needed.

Hi,

I tested the Bootstrap theme with Kendo UI Button for Angular and Bootstrap predefined button styles (https://stackblitz.com/edit/angular-as8wa3?file=app/app.component.ts), however I am not able to reproduce the illustrated issue. Could you please check if there are any custom CSS rules in your application which may influence the default button styling? Or is it possible to modify my example and demonstrate the problem - this way I would be able to check what exactly is going wrong and provide concrete recommendations? Thank you in advance for your cooperation.
