When the project uses Joomla! 3 + Seblod, then there is no sense what the CSS framework is used. In Seblod ALL customized to suit any needs. We use UIKit for their projects and are very happy. With UIKit nicer to work and it is more flexible than Bootstrap. I think the Seblod developers must create templates so that they can be used with any CSS framework, and not to focus on the use of only Bootstrap.
Correct me if I am doing wrong, but I guess a lot of HTML-Markup comes out from plugins. In this case you have to rewrite the plugin markup to Bootstrap classes. For example if you want to rewrite the form-inputs to the Bootstrap Form-Markup-Classes without all the Seblod Divs around you have to change the HTML-Markup where it comes from - and I guess this will be a plugin. But I am not sure.
sorry for the late response! I dont mean the divs around - I know that they come out from the template and therefore I only use custom templates with Bootstrap 3 classes. What I mean is the HTML-markup of the field itself. For example you create a contact form with Seblod and you have a lot of inputs for name, email, subject and so on. If you output these formfields in your custom form template in the way of $cck->get('myformfield')->form you have only the Seblod classes in it, but not the Bootstrap css-classes. I use PHP to manipulate the classes according to Bootstrap classes. This is what I mean. The HTML markup of the field itself and this markup comes out from the field plugin (as far as I know).
yes, the field markup comes from the field plugin.
You can control it by taking the "_markup.php" file from template seb_one. Copy it to your_template/fields folder. Rename it to "markup.php". Follow the instructions in the file to adjust it for your needs.
