How to format column with and background of a matrix?

Hi!

I'd like the columns in my matrix to all be the same width but am having trouble making this happen. I've tried the following code and adjusting the column width but it didn't make a difference.

form-matrix-values {

padding-left: 8px;

padding-right: 8px;

}

/*-first column width-*/

.form-matrix-values .form-textbox {

width: 100px;

}

/*-2nd column width-*/

.form-matrix-values +

.form-matrix-values .form-textbox {

width: 200px;

}

I'm also wondering if there's a way to remove the grey background of the matrix?

Here is a screenshot of my matrix:

Thanks!

Please inject the following CSS code to adjust the width: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes 

#id_91 table.form-matrix-table input{

width: 60px !important;

}

#id_70 table.form-matrix-table input{

width: 60px !important;

}

Result:

On regards of the color, what background color do you want to set?

1) In order to style the column headers, use the following code:

.form-matrix-column-headers {

    border: 1px solid {Anycolor};

    background: {Anycolor};

}

Example:

.form-matrix-column-headers {

    border: 1px solid yellow;

    background: yellow;

}

2) This would be the code for the row headers:

form-matrix-row-headers {

    border: 1px solid #ccc;

    background: orange;

}

3) This would be the CSS code for matrix values:

form-matrix-values {

    border: 1px solid #ddd;

    background: #00a0f0;

}
