Header 100% width

Hi Guy. If you make your image the same width as your site, you can use this css to adjust it:

#header .pad, .site-title {
  padding: 0;
}
.site-title a img {
  max-height: 400px;  /* this is the height of your image; may need to use !important */
}

Or you could remove the logo in Theme Options and try this css to set a background image in the header. If your image is less than 400px in height you’ll need to make adjustments:

/* set header background image; image size is site width x 400px */
#header {
  background: url(http://yoursite.com/wp-content/uploads/yourimage.jpg) no-repeat center top;
  height: 400px;
}

/* push the header menu down */
#header .pad {
  height: 340px;
}

/* reduce content margin to align with bottom of menu */
#page {
  margin-top: -11px;
}

/* media queries to accommodate above changes */
@media only screen and (min-width: 720px) and (max-width: 960px) {
  #header .pad {
    height: 341px;
  }
  #page {
    margin-top: 0;
  }
}
@media only screen and (max-width: 719px) {
  #header .pad {
    height: 400px;
  }
  #page {
    margin-top: 50px;
  }
}
