Customising font in CSS Stylesheet for form labels

Hi
Can you please help me because i tried to make a new post in the forum but my account doesn't let me read anything.
It seems i might have found the place where i should put the css entering the following but nothing is happening.
In the CSS style sheet, i put

.label .gfield_label {
color: #black;
font-weight: bold;
font-family: Questrial, Verdana, Geneva, sans-serif;
font-size: 16px;
!important
}

And in the css class name field in the form i put:

.label .gfield_label

This is the only CSS stylesheet where it seems that it should be so what should I do? It says in the Gravity Forms documentation that I can customize the colors and fonts but I can't, does anyone know if is there any other way?

Many thanks

Magali

Hi
Thank you for your reply. Which CSS stylesheet should i enter it in as there are several: editor-style.css, font-awesome.ie.7.css, font awesome min.css, ie.8.css, pretty photo.css, responsive.css
What sort of link should i send to show how the themes css and the forms css are interacting?
Thank you
Magali

Hi thank you. Adding the code to the style.css has worked however it doesn't control the bold option, I have removed the bold related code but it is still bold. I have changed the code in both the theme's style and the gravity forms admin.css but nothing makes a difference. Have you got any thoughts as to what could create that?
Thank you

No I am not using Catching plug-ins. Also since i changed that code, it seems that the rest of the headings and body text has also gone smaller but when i change it back the headings still seems smaller.

Here it is, it's the form at the bottom.

Thank you

Yes i want the headings of the labels not to be bold to match my contact form. HI I changed it to what you said but it is still bold. I am not sure what is going wrong.Thank you.

Hi Thank you for your help.
I did what you said and this is the code i have used.
gform_wrapper .gfield_label {

color: #040300;
font-weight: normal !important;
font-family: Questrial, Verdana, Geneva, sans-serif;
font-size: 14px;

}

I have put it at the bottom of the theme's styles.css and the admin.css for gravity forms but still the label headings are bold so it is overriding it somewhere else. I am not sure what else to do?
THank you

I am dealing with the same issue, I used the above codes and placed them in my css style sheet at the bottom and it worked great. BUT, the bottom labels of the input forms did not change. How do I do that?
