Previously I've been using kendo.bootstrap-v4.min.css, which is now throwing a 404 with 2023.1.314.

Documentation specifies the following which also throws a 404.

http://https://docs.telerik.com/aspnet-core/installation/adding-client-side-resources/cdn-service

<link href="https://kendo.cdn.telerik.com/2023.1.314/styles/kendo.bootstrap-main.min.css" rel="stylesheet" type="text/css" />

Heath

Hi Heath,

Thank you for your feedback. Since R1 2023 SP1 (v 2023.1.314) we are distributing the SASS themes under the themes' CDN which follows their semantic versioning, avoiding duplicate distribution of the same files on Kendo CDN under the Kendo UI versioning. The correct path to the bootstrap theme is shown in the following section in the article - https://docs.telerik.com/aspnet-core/installation/adding-client-side-resources/cdn-service#using-the-cdn-in-your-project . Posting it here for clarity as well:

<link rel="stylesheet" href="https://kendo.cdn.telerik.com/themes/6.2.0/bootstrap/bootstrap-main.css" />

It includes themes, then themes' version, then the theme package and last the name of the CSS file. Note that the file name does not start with "kendo." anymore and there is no min version of the file.

We will update the rest of the info in the article to point to the correct path.

Hi,

We use local files and I noticed there are no more minified css files included in the Telerik UI for ASP.NET Core installation folder or download archives. Can I just confirm that you are no longer providing minified css files and it is OK to use the bootstrap-main.css file in production?

Kind regards,

David

Hi David,

Indeed, starting with the 2023 R1 release the minified version of the css files are no longer provided. You will need to use the non-minified versions as bootstrap-main.css.

If you decide to use CDN You can take a look at the following forum thread where the new structure is explained in more details:

- https://www.telerik.com/forums/version-2023-1-314-missing-css-on-cdn#5639805

I hope you will find the provided infromation helfpul.

Thanks Neli,

Do you have any more information on the reason behind no longer providing minified css files? My understanding is that minification improves page rendering times. Do you believe the impact of using non-minified css is negligible i.e. we can use the non-minified css files in production, or is the expectation that we are now responsible for css minification?

It would be good if this was documented somewhere to help us make decisions on how to incorporate the change into our systems.

Kind regards,

David

Hi David,

Previously the stylesheets were minified along with the scripts. However, currently the stylesheets are distributed from the themes package which is not minified. Using the non-minified stylesheets should not have an impact on the performance as the files are not huge. However, you can still minified the stylesheets on your end if you prefer to use a minified version.

Hi Neli,

I am currently upgrading from KendoUIProfessional 2019 to 2023. I have noticed that in the new content folder there is no longer a kendo.common.min.css file nor is there a kendo.blueopal.min.css. What files in the 2023 content folder should I refer to in order to replace these?

Thanks!

Hi Sven,

The mentioned files are missing as after the 2023 R1 release the Kendo Less Themes are no longer supported and shipped with the product. I would suggest to take a look at the following article regarding Less to Sass Theme Migration where you can find also the Sass themes corresponding to each Less theme.

- https://docs.telerik.com/kendo-ui/styles-and-layout/less-themes/less-themes-migration

I hope this helps.

Regards,

Neli

I updated the version number from 2021 to 2023 and now I have 

GET
https://kendo.cdn.telerik.com/2023.2.718/styles/kendo.bootstrap-v4.min.css
net::ERR_ABORTED 404

how should we update this one to the latest version?

what are the themes and how to get the versions (6.0.0) by ex?

where are the MINimized css?

Hi Serge, 

You can check the list with the corresponding SASS to LESS themes:

- https://docs.telerik.com/kendo-ui/styles-and-layout/less-themes/less-themes-migration#how-do-i-know-which-sass-theme-corresponds-to-my-current-less-theme

As noted in the section: The Bootstrap and Material Less themes will not have their own Sass swatches. Instead, use the dedicated Bootstrap and Material Sass themes.

The CDN for the Bootstrap-3 swatch is:

https://kendo.cdn.telerik.com/themes/6.6.0/bootstrap/bootstrap-3.css

OR if you prefer to use the main swatch:

    <link href="https://kendo.cdn.telerik.com/themes/6.6.0/bootstrap/bootstrap-main.css" rel="stylesheet" />

I would also suggest taking a look at the article regarding Kendo UI for jQuery and Kendo UI Sass themes versions compatibility:

- https://docs.telerik.com/kendo-ui/styles-and-layout/sass-themes/compatibility

Regards,

Neli
