How to Apply Font Weights
You can apply font weights in two ways:
Global Application
Use the right-hand settings panel to apply a font weight to an entire section.
This ensures consistent styling across all related text blocks.
Local Application
Use the top toolbar pop-up editor to change the font weight for individual text blocks.
Tips for Using the Pop-Up Editor
Reset Formatting:
If you want to undo changes made through the pop-up text editor:
Highlight the text.
Click the "Reset Formatting" button.
This button is found in the dropdown menu on the far right of the editor.
This action clears custom styles and reverts your text to default settings.
Note: Keep in mind that the pop-up editor will override text elements such as font size and font choice. Use this editor for detail work and fine-tuning. For consistent styling, apply global text changes using the right-side menu in the builder.

Known Limitations
If your font folder lacks a specific weight (e.g. 600 Semi Bold), Knak will use the closest available weight (e.g. 700 Bold).
This fallback applies to any missing weights.
Tip: To avoid mismatches, upload every required font weight during your custom font request.
