Hi, Figma community!
It would be great to support dotted/dashed underlines in Figma.
In CSS, it’s supported through the text-decoration-style attribute - see [text-decoration-style - CSS: Cascading Style Sheets | MDN].
Please vote 
for this feature!
We hope to see it supported one day in Figma. 
For short one-line texts, you can simulate any sort of underline with auto layout. But for more complex texts, that won’t be possible. You will need to manually place underlines under words.
I think it would be better to turn this post into a suggestion and put it in the #product-ideas category so people can vote for this change. Feel free to edit your post for that. 
Thanks for the suggestion! Moved to the Ideas section.
Can underline styling be added? There are a number of CSS styles that can be applied, and unfortunately, none are exposed to the designer. As text links can be added in designs, it is important for those designing interfaces to ensure that they are styled correctly - the default one in Figma is very feint. and closer to the text than most browsers.
Voted! This would help bridge the gap between figma and CSS/build. Please figma 
With CSS, you can change the colour of the underline, size/thickness, etc. and have effects like an underline underlapping the text. It’s difficult to create a workaround using a line or shape when creating a component, or using Auto Layout.
Would be awesome to have more options in a Text Style to style underlines.
It means I can’t use a single text style for a DS component when applying a hover interaction.
Here’s a GIF example, I don’t want the text style to revert to the (broken) text style I want the hover state to hold the new font, the interaction should just apple a decoration over my overridden text style.
Patiently waiting for this one. ATM I have to build complicated text underlines with auto-layout where I build three layers for any wrapping text. Gets laborious!
Yes ++ on this one.
Currently we’re looking to implement Links with wavy underlines. It’s mostly possible with Auto Layout, but without some complex tricks:
I would love to see this as well! 
To add to this, we really need to be able to adjust the offset of the underline, just like we can in CSS!
our team needs the ability to offset underlines — plug for that 
This would be such a helpful feature!
Also to change the thickness of an underline, this would be super helpful!
text-underline-offset
text-decoration-thickness
these can also be added please 
This would have been super helpful!
Yes please! +1
Give us all the options that exist in css.
+1 for being able to style the underline text separately from the text style itself.
After all this time, how is this still not a thing? It’s basic CSS text styling
Underline and strikethourgh were basic decoration specs in 1996 (CSS1 - 27 years ago!). It was 20 years old when Figma was born…
