HTML / XHTML. Code:

<div class="parent">

<div class="child">

<div class="childcontent">CSS vertical alignment</div>

<div class="childcontent"><img src="image.jpg" width="68" height="68" alt="Image" /></div>

<div class="childcontent">CSS vertical alignment</div>

</div>

</div>

CSS. Code:

.parent {position: relative; left: 0px; top: 0px; height: 200px; display: table;}

.child {position: relative; left: 0px; top: 0px; display: table-cell; vertical-align: middle;}

.childcontent {position: relative; left: 0px; top: 0px;}

Note: .parent and .childcontent may be floated left ("float: left;") or not, but .child must be without "float: left;" for this method of CSS vertical alignment to work.

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.

Lynx. Web data extraction

 

Aside from browsing / displaying web pages, Lynx can dump the formatted text of the content of a web document or its HTML source to standard output. And that then may be processed by means of some tools present in Linux, like gawk, Perl, sed, grep, etc. Some examples: Dealing with external links Count number of external links Lynx sends list of links from the content of a web page to standard output. Grep looks only for lines starting with "http:", sends the result further again to grep that picks lines not starting with "http://compmiscellanea.com" and "http://www.compmiscellanea.com" (external links of the web page) out of it, wc counts the number of links extracted and displays it: lynx -dump -listonly "elinks.htm" | grep -o "http:.*" | grep -E -v "http://compmiscellanea.com|http://www.compmiscellanea.com" | wc -l Find external links and save them to a file Lynx sends list of links from the content of a web page to standard output. Grep looks only for lines starting with "http:", sends the result further again to grep that picks lines not starting with "http://compmiscellanea.com" and "http://www.compmiscellanea.com" (external links of the web page) out of it and saves them to a file: lynx -dump -listonly "elinks.htm" | grep -o "http:.*" | grep -E -v "http://compmiscellanea.com|http://www.compmiscellanea.com" > file.txt Find external links, omit duplicate entries and save the output to a file Lynx sends list of links from the content of a web page to standard output. Grep looks only for lines starting with "http:", sends the result further again to grep that picks lines not starting with "http://compmiscellanea.com" and "http://www.compmiscellanea.com" (external links of the web page) out of it, sort sorts them and uniq deletes duplicate entries. The output is saved to a file: lynx -dump -listonly "elinks.htm" | grep -o "http:.*" | grep -E -v "http://compmiscellanea.com|http://www.compmiscellanea.com" | sort | uniq > file.txt Dealing with internal links Count number of internal links Lynx sends list of links from the content of a web page to standard output. Grep looks only for lines starting with "http://compmiscellanea.com" and "http://www.compmiscellanea.com" (internal links), wc counts the number of links extracted and displays it: lynx -dump -listonly "elinks.htm" | grep -E -o "http://compmiscellanea.com.*|http://www.compmiscellanea.com.*" | wc -l Find internal links and save them to a file Lynx sends list of links from the content of a web page to standard output.

Grep looks only for lines starting with "http://compmiscellanea.com" and "http://www.compmiscellanea.com" (internal links), sort sorts them and uniq deletes duplicate entries. The output is saved to a file: lynx -dump -listonly "elinks.htm" | grep -E -o "http://compmiscellanea.com.*|http://www.compmiscellanea.com.*" | sort | uniq > file.txt The reason behind using "lynx -dump -listonly" instead of just "lynx -dump" is that there may be web pages with plain text strings looking like links (containing "http://" for instance) in the text of the content, as it is the case with http://www.kompx.com/en/elinks.htm page.
