I am trying to get Material Design Lite text field to work and I have an issue where the bottom colored line has a slight 3-4 px gap between the gray starting line. Any MDL
I did face the same issue with MDL when used with boostrap and turns out the boostrap css file adds a margin of 5px to its bottom for the Label elment which creates a 5px gap.
JSFiddle-Recreating the issue
Code snippet from Bootstrap.css file
label {
display: inline-block;
max-width: 100%;
margin-bottom: 5px;
font-weight: bold;
}
Fix would be reduce the margin-bottom of the label element to 0px.
Fix- JsFiddle
.mdl-textfield__label{
margin-bottom:0px;
}
Hope this helps.
