I created a simple html source, and applied a small CSS style sheet to it:
html {
width: 100%;
}
body {
font-family: Calibri, Tahoma, Geneva, sans-serif;
padding: 20px;
}
pre {
padding: 0;
margin: 0 auto;
border: 1px solid #888;
font-family: Menlo,Monaco,Consolas,monospace;
color: #000;
width: 80%;
overflow: auto;
}
pre li { white-space: pre; }
ol { margin-top: 0; margin-bottom: 0; /* IE indents via margin-left */
color: #979797; background: #E3E3E3; }
.li1 { background: #F5F5F5 }
.li2 { background: #eee }
I have an ordered list inside a pre-formatted tag. Every other list
element is either given the class attribute li1 or li2 (the purpose of which is to alternate the colors). The list elements need the white-space: pre because the white space before and after the text node is important. The pre is to be 80% of the containing
element (which ends up being 80% of the window's width). In the event of overflow in the x dimension, I want scrolling.
I did all this in the above CSS, and it almost works. The issue I am having is that the background colors of the list elements don't extend with the content. They seem to be capped to the original width of the pre and/or ol
element as demonstrated in the following picture where I scroll all the way right as possible:
I tinkered with the CSS for a while, but I cannot determine the root cause for this or the fix. Looking for some advice on this one, thanks.
Complete source with the issue is as below, NOTE: to would-be editors of the below code the pre
element is intended to be on a single line as it's pre-formatted text, and formatting it otherwise would change things.
