Hi, is that possible to write css style in object tag
<a href="#" style="concrete's css code">Sample Link</a>
If so, there is a magical FREE addon available that can help you with this:
This addon forces the core Concrete user interface (both jquery and CSS styles) to load for the page view.
I hope this helps.
Or, if you are using the standard Content block, you will want to first set the WYSIWYG editor setting to advanced in the dashboard (if you haven't already done s). Then, when you add a content block, you can use the HTML option to edit the code.
If you are using any other type of block, click on the "Design" option, and you will see that you can add your own custom CSS this way as well.
If you want to get more complex or more targetted, you could just write html blocks and put style attributes in the content in the html block.
Another solution is my Style Quickie block. I often use it to add some very targetted styling to elements of a page or to override a few aspects of a theme that would not otherwise be configurable.
