How to make logo go ........

[slumpy]

You lost me M, sorry. My brain doesn´t stretch as far as this.
Their is no global.css in (Edit Stylesheet: Advanced Mode)
But thanks for trying to help me, I really appreciate it.

^ stylesheet opens in Simple Mode when we click on the global.css
at the top there will be a tab named Edit Stylesheet: Advanced Mode. clicking on it opens global.css for full edit

ok, got that far, now where at the beginning to I insert.

.logo {margin-top: -20px;
margin-left: -20px;
width: 100%;}

The first few lines are as follows.
body {
background: #efefef;
color: #000;
font-family: Verdana, Arial, Sans-Serif;
font-size: 13px;
text-align: center;
line-height: 1.4;

^ you can make a empty line at the top and insert the suggested code like below

.logo {margin-top: -20px;
margin-left: -20px;
width: 100%;}

body {

or ACP>Templates & Styles>Themes>MyBB Default

Any help please..

Templates & Styles is a tab/category and not an option.
