Changing font colour

Hi,
I've noticed that there is one area to change the colours of the links and headers:
a {
text-decoration:none;
color:#;
}

Just wondering if there is a way to separate them? I tried to do it individually by header (h1, h2, h3 etc) but that hasn't changed anything.

Also, there is a section before the comments on each blog page that says 'leave a reply'. In the comments php it says "leave a comment". I have changed this to what I want it to say but the 'leave a reply' code overwrites this. Can you please tell me where I can find this so I can change/delete it?

Thanks!

 

Also, the code from previous threads (below) didn't change anything when pasted into the 'custom CSS" cheers!

.content-bar .post .post_title a{
color:red;
}
.content-bar .post .post_meta li{
color:red;
}
.content-bar .post .post_meta a{
color:red;
}

 

1.For your first issue

Please explain your problem with the help of screenshot, where you want to change the color, so that we can give you the exact solution.
and also share the link of your website.

2.For your second issue

"Leave a reply" is a default text show by WordPress therefore it is not possible to change it, If you want to delete this text then

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

#respond h3{
display:none;
}
