CSS DzR主样式表（第一部分，重置）

Posted 2021-05-23

/**************************************************************************************************/
/*This stylesheet was created for HTML 4.01 using CSS 3 (and older)
/*Tested on Windows versions of Firefox 1.5-3.0, IE 6-7, Safari 3.2, Opera 9.2-9.6, and K-Meleon 1.5
/*
/*I've put helpful classes into a separate stylesheet. PLEASE CUSTOMIZE THAT STYLESHEET AS NOTED!
/*IE-specific stylesheets include fixes or fallbacks for both of these stylesheets, so comment out relevant rules
/* if you won't be using the classes.
/*
/*Because of too many browser inconsistencies, I have:
/*- left the styling of form elements up to the browser (for the most part).
/*- not set the outline property on anything (e.g., `:focus`).
/*
/*Elements included:
/*  Obsolete:
/*     app, bgsound, blink, comment, listing, marquee, multicol, nobr, plaintext, sound, spacer, wbr, xmp
/*  Deprecated:
/*     applet, basefont, center, dir, font, isindex, menu, s, strike, u
/*  Non-standard:
/*     embed, noembed
/*  Standard:
/*     a, abbr, acronym, address, area, b, base, bdo, big, blockquote, body, br, button, caption, cite, 
/*     code, col, colgroup, dd, del, dfn, div, dl, dt, em, fieldset, form, frame, frameset, h1, h2, h3, h4, h5, h6, 
/*     head, hr, html, i, iframe, img, input, ins, kbd, label, legend, li, link, map, meta, noframes, noscript, 
/*     object, ol, optgroup, option, p, param, pre, q, samp, script, select, small, span, strong, style, sub, sup, 
/*     table, tbody, td, textarea, tfoot, th, thead, title, tr, tt, ul, var

Note, however, that these will now be more tedious to override in other stylesheets.
