okay – I figured it out and thought I’d post the fix here so others could benefit.
In the StyleSheet template of the theme there’s a section down toward the bottom called “Forms”. In the forms section, look for Input, Select, Textarea. I made mine look like this…
input, select, textarea {
border:1px solid #ddd;
color:#888;
padding:9px 10px;
width:auto;
box-sizing:border-box;
}
…and all the little buttons were happy ??
