I've been working on a template using CSS, but I can't get the right side bar to line up flush like the left side bar is. It's driving me up the walls because I've been trying to mess with the right side bar's margins to fix it, but if I go -145 it drops below the rest of the content and sits on the left side. I've also included the files as attachments in a zip file. Any help would be very much appreciated. :-)

Several errors:

- 0px is not a valid style. use 0 for all zero values, with no unit of measure. 0 with a unit of measure makes a Firefox error. It creates a value which is not 0 instead.

- Don't put size styles (width, height) and nonzero surrounding styles (margin, border, padding) in the same style or tag. It won't work right, making incompatibilities in browsers. IE crams the surrounding styles INSIDE the width, Firefox and other standards-complying browsers put the surrounding styles OUTSIDE the width. If you need both, nest a tag with one kind inside a tag with the other kind.

- Use percentages for widths, instead of pixels or points.

Hi Metal,

Let me know if it works.

Hmm.. I'll take a look at it again, Midi. I was lead to believe in a class I took that you can have 0px since it's pixels.. hehe.. Thanks for trying Macneato, but I wanted to leave the left bar on the left side and just align both on their separate sides to the edge of the header.

Several errors:

- 0px is not a valid style. use 0 for all zero values, with no unit of measure. 0 with a unit of measure makes a Firefox error. It creates a value which is not 0 instead.

- Don't put size styles (width, height) and nonzero surrounding styles (margin, border, padding) in the same style or tag. It won't work right, making incompatibilities in browsers. IE crams the surrounding styles INSIDE the width, Firefox and other standards-complying browsers put the surrounding styles OUTSIDE the width. If you need both, nest a tag with one kind inside a tag with the other kind.

- Use percentages for widths, instead of pixels or points.

Could you give me an example of a nested tag? I think I understand what you mean, but I want to be sure.

Nvm.. I fixed the problem myself. I just changed the content margins and adjusted the left/right side bar margins. Works like a charm now. Thanks for the ideas everyone.

#content {
    margin: 0px 200px 30px 175px;
    padding: 0px 30px 20px 30px;
    width: 440px;
    float: left;
    text-align: justify;
    text-justify: newspaper;
}

#left {
    margin: 0px 0px 30px -900px;
    padding: 5px 5px 20px 5px;
    width: 150px;
    float: left;
    background: #585858;
    border-top: 10px solid #222222;
    border-bottom: 5px solid #585858;
}

#right {
    margin: 0px 0px 30px -160px;
    padding: 5px 5px 20px 5px;
    width: 150px;
    float: left;
    background: #585858;
    border-top: 10px solid #222222;
    border-bottom: 5px solid #585858;
}
