Maybe one could determine the line width based on the xHeight member of the font? Just an idea. Cheers, Johannes

patch: <s> line appearance

by corvid＠lavabit.com

I was thinking that large text with a thin line through it looks odd. Turns out that there was also a problem with causing the <s> line to be too high. This looks about right to me with the few fonts I have around. I'm attaching an example html file as well. PS Might be good to go through that area of the code one day to see what opportunities there are to make it clearer...

I think the original test, that I now moved to Html_tag_open_a() is ok: if (!id || strcmp(nameVal, id)) { if (id) BUG_MSG("'id' and 'name' attribute of <a> tag differ\n"); Html_add_anchor(html, nameVal); } I.e. do something if id is not set or id and name differ. Then if they differ output a warning. Add an anchor for the new string. Cheers, Johannes

BTW, http://www.validome.org/lang/ge/errors/MISC/3005 says that they must be equal for the above mentioned elements only. I don't know what's the rule for other elements with "name" attr. though. -- Cheers Jorge.-

Right, that's the idea. Maybe: if (id && strcmp(nameVal, id) == 0) { BUG_MSG("'id' and 'name' attribute of <a> tag differ\n"); } else { Html_add_anchor(html, nameVal); } -- Cheers Jorge.-

It has already been called with the same value from Html_parse_common_attrs(). We could put the corresponding code that is currently in Html_tag_open_a() in a new function Html_handle_name_attr() and call that from all elements that allow a "name" attribute. Cheers, Johannes
