{"rowid": 321, "title": "Tables with Style", "contents": "It might not seem like it but styling tabular data can be a lot of fun. From a semantic point of view, there are plenty of elements to tie some style into. You have cells, rows, row groups and, of course, the table element itself. Adding CSS to a paragraph just isn\u2019t as exciting.\n\nWhere do I start?\n\nFirst, if you have some tabular data (you know, like a spreadsheet with rows and columns) that you\u2019d like to spiffy up, pop it into a table \u2014 it\u2019s rightful place!\n\nTo add more semantics to your table \u2014 and coincidentally to add more hooks for CSS \u2014 break up your table into row groups. There are three types of row groups: the header (thead), the body (tbody) and the footer (tfoot). You can only have one header and one footer but you can have as many table bodies as is appropriate.\n\nSample table example\n\nInspiration\n\nTable Striping\n\nTo improve scanning information within a table, a common technique is to style alternating rows. Also known as zebra tables. Whether you apply it using a class on every other row or turn to JavaScript to accomplish the task, a handy-dandy trick is to use a semi-transparent PNG as your background image. This is especially useful over patterned backgrounds. \n\ntbody tr.odd td {\n     background:transparent url(background.png) repeat top left;\n }\n\n * html tbody tr.odd td {\n     background:#C00;\n     filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(\n          src='background.png', sizingMethod='scale');\n }\n\nWe turn off the default background and apply our PNG hack to have this work in Internet Explorer. \n\nStyling Columns\n\nDid you know you could style a column? That\u2019s right. You can add special column (col) or column group (colgroup) elements. With that you can add border or background styles to the column.\n\n<table>\n     <col id=\"ingredients\">\n     <col id=\"serve12\">\n     <col id=\"serve24\">\n ...\n\nCheck out the example.\n\nFun with Backgrounds\n\nPop in a tiled background to give your table some character! Internet Explorer\u2019s PNG hack unfortunately only works well when applied to a cell.\n\nTo figure out which background will appear over another, just remember the hierarchy:\n\n (bottom) Table \u2192 Column \u2192 Row Group \u2192 Row \u2192 Cell (top)\n\nThe Future is Bright\n\nOnce browser-makers start implementing CSS3, we\u2019ll have more power at our disposal. Just with :first-child and :last-child, you can pull off a scalable version of our previous table with rounded corners and all \u2014 unfortunately, only Firefox manages to pull this one off successfully. And the selector the masses are clamouring for, nth-child, will make zebra tables easy as eggnog.", "year": "2005", "author": "Jonathan Snook", "author_slug": "jonathansnook", "published": "2005-12-19T00:00:00+00:00", "url": "https://24ways.org/2005/tables-with-style/", "topic": "code"}
