I have a List (radio) question type and I want to align the radio button with the text (in this case lowering it). I'm not able to do this in LS 3, but was able to in LS 2.5.

What theme are you using? Can you provide a screenshot?

Using the base Vanilla survey theme.

Try updating to the latest version. This is what I see using the vanilla theme in version 3.15.1.

I made some progress, in LS 3.0. Note: I can also make my example look aligned when
I reduce the text size from 24px to 14px.

I inspected the page in Chrome and modified the line as follows, it worked:
[added: style="line-height:15px;"]
<label style="line-height:15px;" for="answer574568X34X186A1" class="control-label radio-label">
<span style="font-size:24px;">I felt totally unsupported</span>
</label>
for image of results see: ThisWorkedRadBtn.png
for image of the code see: InspectionCodeChange.png

To implement, I've added to custom.css:
.radio-label {

line-height: 15px;

padding-top: 8px;

padding-bottom: 3px;

}

The radio button aligns with the text aligns.
However, the css override does not work the same as the direct code change:
the radio button fill dot position remains unchanged, therefore making it not in the center.

I'm not able to make the fill dot move down, when option is clicked.

Can you give a link to a sample survey so we can see the source?

here is the link:

ls.dev.myontarioicu.net/index.php?r=surv...x&sid=716188&lang=en

Add this to the end of custom.css:

Thanks for your help Tony, that worked perfectly.
