I get

Error 404: File Not Found

when I browse link you gave me

Is working, I tested just now.

www.ketamy.com.br/v3/

Please help me, I need this to finish the site.

Add this to bottom of template_css.css:

a.readmore{
display: inline-block;
padding: 4px 12px;
margin-bottom: 0;
font-size: 14px;
line-height: 20px;
color: #fff;
text-align: center;
vertical-align: middle;
cursor: pointer;
background-color: #33ccff;
}

p.readmore a:hover, p.readmore a:focus {
background-color: #8c8c8c;
}


properties are for our default style, adjust colors or simply type your style properties from start

Great !!

There's one more problem, in chrome the site appears in the size I want, but in firefox and explorer it appears larger.

I did a search and found nothing about it. Can you please help me?

It appears same maybe you set something in your IE and FF
