Search Button Color in Framework

Hello, I have been trying to fix an issue i've run into with the search button. I tried to just add a background color to my css to override the standard color but there is some type of standard gradient that i can't pinpoint how to get rid of . I want it to be a solid green, even my own gradient but there is some styling i can't figure out what to remove. Currently the button area sits half covered in modern browsers (-15px something?), and in IE i get my normal green bg. Not sure if i messed something up when editing other stuff?

i figured it out.

thanks!

removed:

input[type=button], input[type=submit], input[type=reset], button {   
    cursor: pointer;   
    background-color: #F5F5F5;  
    background-image: -ms-linear-gradient(top, #FFF, #E6E6E6);  
    background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#FFF), to(#E6E6E6));  
    background-image: -webkit-linear-gradient(top, #FFF, #E6E6E6);  
    background-image: -o-linear-gradient(top, #FFF, #E6E6E6);  
    background-image: linear-gradient(top, #FFF, #E6E6E6);  
    background-image: -moz-linear-gradient(top, #FFF, #E6E6E6);  
    background-repeat: repeat-x;  
    filter: progid:dximagetransform.microsoft.gradient(startColorstr='#FFF', endColorstr='#E6E6E6', GradientType=0);  
    filter: progid:dximagetransform.microsoft.gradient(enabled=false);  
    box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.2), 0 1px 2px rgba(0, 0, 0, 0.05);  
    padding: 6px 10px;  
    width: auto;  
}  

Glad to know you were able to implement the changes :)
