Change from 100% to fixed width

Hi there, I checked your site and see that it is using Espressionista, not Reddle. Did you choose a different theme or have you not yet switched over to Reddle?

Just in case, what you would want to do would be to create a child theme for your changes and then open the orginal stylesheet and copy out all the CSS, except for the @media rules at the bottom and paste it into the child theme CSS file. Next, remove the
@import url("../reddle-wpcom/style.css");
from the top of the child theme CSS file.

Next, find #page rule in the child theme CSS and add a width declaration
width: 900px;

Save and your site should then be fixed width. I tested on my test site and that was what worked for me.

For reference:
Child Themes
Child Theme creation plugins

Also, you can try adding this at the bottom of your child CSS, or find these rules in the copied CSS and add in/modify them for the content and sidebar width.

.secondary #primary {
    width: 540px;
}
.secondary #content {
    margin-right: 0;
}
#main .widget-area {
    width: 270px;
    margin-right: 6%;
}
#main .widget-area .widget {
    margin-left: 30px;
}

The above was sort of a rough pass on things. You may want to edit if it isn’t exactly what you are looking for.

Sorry, been busy.

Yes, I did install another theme, but now I’m back to Reddle.

If I remove the @media the theme will not be responsive to different devices, right? Any way to get around this, having a fixed width for the computer users and still showing the site to mobile users without them having to scroll sideways?

That’s great, and in general, removing the media queries would make the theme fixed, but in some instances “max-width” declarations outside of the media queries have to be changed to straight widths, and any % widths typically you would want to change to fixed also.
