Hi Michael,
Thank you for contacting Syncfusion support.
We want to inform you that Syncfusion theme files have style for Syncfusion Blazor components only and we just included the color scheme and dimensions standard of Bootstrap 4 as we did for other third party CSS frameworks. So, we can use Syncfusion components with any third party CSS frameworks layout systems.
Since our CSS custom classes are starting with “e-”, it will not be affected by any third party styles. Also, we request you to check our Theme Studio to generate the style file required components that you can find from the below link.
We request you to share more details if you require any component specific customization for clear understanding of your need in case we misunderstood your point.
Please get back to us if you have any concerns.
Regards,
Jesus Arockia Sankaran S
