Can the tab spacing be customized within a <pre> tag using CSS to specify the number of pixels?
For instance, imagine displaying a code snippet within a <pre> on a webpage:
function Image()
{
this.Write = function()
{
document.write(this.ToString());
return this;
};
...
}
Image.prototype = new Properties();
...
Is it feasible to adjust the tab indentation amount using CSS?
If not, are there any alternative solutions or workarounds available?
Although the previous conversation touched on historical context, it's essential to adapt to the present circumstances. For updated information and potential solutions, check out this resource: Modifying Tab-Length?
Attention to admin: There may be similarities with the referenced inquiry.
According to the CSS 2.1 specifications, tabs (U+0009) are displayed as a horizontal shift aligning the next glyph with the tab stop. These tab stops occur at intervals that are multiples of 8 times the width of a space (U+0020) in the block's font.
CSS3 Text echoes similar rules for handling tabs.
In HTML 4.01, the PRE element interprets the horizontal tab character (decimal 9) as the minimum number of spaces needed to line characters up along tab stops every 8 characters. However, it is not recommended to use horizontal tabs in preformatted text due to potential misalignment issues when editing and setting different tab-spacing values.
To avoid problems with leading tabs, simply replace them with spaces.
