How to edit fonts and colors on blog page only

[fatcatgraphics]

Hi ,
Im trying to apply the following css to my blog posts only. but they affect the entire site. The body img mostly. My images are all massive. I tried adding .blog in front but that didnt do it.

Thanks for your help,
Rena

.entry-content {
font-family: Arial,“Helvetica Neue”,Helvetica,sans-serif!important;
font-size: 18px!important;
color:black;
}
body .format-standard .entry-wrap {
width:976px;
margin:0 auto;
}
body img {
width:976px;
margin:0 auto;
}

## UPDATE:

Ive changed it to this:
body.single.single-post .entry-content {
font-family: Arial,“Helvetica Neue”,Helvetica,sans-serif!important;
font-size: 18px!important;
color:black;
width:976px;
margin:0 auto;
}

body.single.single-post img {
width:976px!important;
margin:0 auto;
}

Is this the correct way to do it? seems to be working.
Thanks

Hello Rena,

Yes, that should be right or you can simplify it to:

.single-post .entry-content {
    font-family: Arial,"Helvetica Neue",Helvetica,sans-serif!important;
    font-size: 18px!important;
    color:black;
    width:976px;
    margin:0 auto;
}

.single-post img {
    width:976px!important;
    margin:0 auto;
}

The code above will target the images in the single blog posts.

Hope this helps.
