The version you’re using is missing the update I think. In the latest version the fields are supposed to be 100% width. If you look for this in your CSS (around line 3002) –
.enews-widget input {
width: 100%;
}
It’s supposed to look like this –
.enews-widget input,
.front-page-2 .enews-widget input {
width: 100%;
}
The above can be found in the style.css file inside the responsive/media section –
@media only screen and (max-width: 550px) {
.image-section h4,
.solid-section h4 {
font-size: 34px;
font-size: 3.4rem;
margin-bottom: 20px;
}
.front-page-2 .image-section h4 {
font-size: 24px;
font-size: 2.4rem;
}
.enews-widget input,
.front-page-2 .enews-widget input {
width: 100%;
}
.left-content,
.right-content {
text-align: center;
width: 100%;
}
.left-content .fa,
.right-content .fa {
padding: 20px;
}
}
