How to style the Send button

It looks like your style is being applied (the second one, since it overwrites the first one, as it is more specific).

* To make the button bigger, either add a width and height and set it to the size you want or increase the padding from 5px.

* To make the text bigger, set a font-size attribute.

* The background color #dcdcdc and border color #666 appear to match what you posted above.

Yesterday it was styled, but today it just looks like the default button. Did you remove the styles you posted yesterday from the button? If so, go ahead and add those back and I can take another look.

I found the solution myself ??
For all of view that might need it:

.wpcf7-form .wpcf7-submit {
background:#FF3300;
border-radius:7px;
cursor:pointer;
width:225px;
margin:7px 0;
padding: 10px 18px;
color:#fff;
}
