I tried editing the page using Google Developer Tool.
the textarea background is transparent.
and in google developer tool the CSS codes looks like this below,
:element.style {
width: 95%;
display: inline-block;
z-index: auto;
position: relative;
line-height: 22.4px;
font-size: 16px;
transition: none;
background: transparent !important;
}
As you can see the background is transparent.
Now I want to change it to black.
But google dev tool did not indicate where these codes were?
So how to know what file these codes located?
Or if I will edit the CSS codes in google dev tool, how to save the changes?
Thanks in advance.
