Title: HTML checklist: check your HTML Post by: Daniel Franklin on September 28, 2007, 09:43:01 AM * Do not use <font> element. * Move arrangement attributes (align, valign, width, height) to CSS. * Do not use tables except showing table data. Using tables for visual formatting is acceptable in complex situations only. Max table nesting can not be great than 3. * Move attribute "background" to CSS. * Design of input fields and buttons must be written as class in CSS. * Style table must be written as external file and linked using <link> * All images related to design (not content) move to block with style {background: transparent url("gif") no-repeat;} HTML code * If table cell contains only image with width and height, then don't use these attributes for cell. * Use minimum cols and rows for tables. * All <image> elements must have "width" and "height" attributes. * All <image> elements, which are not links, don't have "border" attribute. * All attributes values must be placed in double quotes. * All tags and attributes names must be in low case. CSS code * Unique elements must have "id" attribute, which is used for style. Repeated elements must use classes. * Determine Links style through styles of (td {}, td a {}, td a:hover {}). a:hover must redefine only changed atttributes. * Determine background color for <body> * Split declarations to groups (fonts, tables, text blocks, divs) * Determine geometrical dimensions in percents or pixels. * All colors values must be as short as possible and in high case (#FFF instead of #ffffff). * All tags and attributes names must be in low case. * All margins and indents must be defined for all browsers. * All classes and identifiers must be named logically with one naming convention. Structure * Use title, description and keywords in header. * All elements with closing tags must have it (ideally, use XHTML 1.0 Transitional/Strict). * Use alt attribute for <image>. If image don't have semantic meaning, alt must be empty. * Use comments before main blocks. * Use standard tags for creating text structure (<h1>-<h4>, <p>, <ul>, <il>, <li> and so one). * Vertical and Horizontal menus must be defined using <li>. * Don't use and . Use <strong> and . * Blocks must be placed in document in the descending order of importance. Blocks location can be defined using CSS.
