Mobile-friendly HTML table


If an HTML table is too wide, having too much data, it may not shrink anymore, it gets wider than the available space and breaks page layout. An horizontal scroll added to the table fixes it up. Example: 12345678910 Table_data_1 Table_data_2 Table_data_3 Table_data_4 Table_data_5 Table_data_6 Table_data_7 Table_data_8 Table_data_9 Table_data_10 HTML / XHTML. Code: <table> <tr> <th>1</th> <th>2</th> <th>3</th> <th>4</th> <th>5</th> <th>6</th> <th>7</th> <th>8</th> <th>9</th> <th>10</th> </tr> <tr> <td>Table_data_1</td> <td>Table_data_2</td> <td>Table_data_3</td> <td>Table_data_4</td> <td>Table_data_5</td> <td>Table_data_6</td> <td>Table_data_7</td> <td>Table_data_8</td> <td>Table_data_9</td> <td>Table_data_10</td> </tr> </table> CSS. Code: table {display: block; overflow-x: auto;} /* Extra CSS, just styling the look: */ table {border-collapse: collapse;} table td,th {padding: 10px; border: 1px #000 solid;} Note: the CSS property of display: block makes the table to occupy only as much space horizontally as it is needed to contain the data without shrinking. Not more, not making itself to stretch from the leftmost to the rightmost sides of the available space - even if width: 100% is added to CSS. Example: 123 Table_data_1 Table_data_2 Table_data_3 [ 1 ] As well as Netscape 9.0. [ 2 ] As well as Netscape 9.0.

CSS horizontal and vertical centering - 2


Centering the content of a web page in the viewable area of a browser by means of CSS. A box to contain the whole content of the page is CSS centered horizontally and vertically: [ Open demo page ] HTML / XHTML. Code: <!DOCTYPE html> <html> <head> <title>CSS horizontal and vertical centering - 2</title> <link rel="stylesheet" type="text/css" href="css.css" /> </head> <body> <div class="spacer">&nbsp;</div> <div class="wrapper"> <div class="pagecontent">&nbsp;</div> </div> </body> </html> CSS. Code: html {height: 100%; margin: 0px;} body height: 100%; margin: 0px;} .spacer {position: relative; top: 0px; left: 0px; height: 50%; width: 100px; float: left; margin: 0px 0px -250px 0px; background: #999;} .wrapper {position: relative; top: 0px; left: 0px; height: 500px; width: 100%; clear: both; background: #a3ddc4;} .pagecontent {position: relative; top: 0px; left: 0px; height: 500px; width: 800px; margin: 0 auto; background: #ff6f6f;} The .pagecontent box is for the page content. It must be of a fixed height and width in units like px's or em's - not in percents. Height and width may be larger than web browser viewable area, but here the more practical case is discussed - when the height and width of .pagecontent are smaller than those of the web browser viewable area. The .pagecontent box is horizontally centered by its "margin: 0 auto". .Wrapper creates a space where .pagecontent is centered horizontally. .Wrapper's width is 100% for centering at various web browser viewable area sizes. The height has to be equal to the one of .pagecontent. .Spacer centers .wrapper with .pagecontent in it vertically inside browser viewable area. Its width may be any. The height is 50% - that places the top edge of .pagecontent vertically in the middle of the browser viewable area. The bottom margin of .spacer equal to half the .pagecontent height centers .pagecontent and its contents vertically in the web browser viewable area of a current height. This method is reliable in all major modern web browsers. It also works in older browsers like Internet Explorer 6 or earlier versions of Maxthon. But the height of box for page content has to be assigned explicitly and if it is changed - the size of .spacer bottom margin must be changed accordingly as well. There is another way of CSS horizontal and vertical centering, with CSS code easier to maintain, even if not suitable for older web browsers: CSS horizontal and vertical centering - 1.
