Problem

I want to merge two or more cells in a HTML Table

Solution

You can use “colspan” or “rowspan” attributes.

<tr><th colspan="3">merged cell</th></tr>
<tr><td>cell1</td><td>cell2</td><td>cell3</td></tr>

<tr><td rowspan="2">merged</td><td>cell2</td><td>cell3</td></tr>
<tr><td>cell4</td><td>cell5</td></tr>

Problem

Where can I find the hosts file in Windows?
I want to add “me-only” domainnames since I am currently developing new web site.

Solution

The hosts file can be found at

C:\Windows\system32\drivers/etc\hosts

Fortunately, the syntax is the same as that of your familiar Linux hosts.
So you can add new entry like,

12.34.56.78     www.example.com

Problem:

I want to add one more classnames to one HTML tag

Solution:

It is not so hard, just put all the classnames with separated by spaces, like

<div class="class1 class2 class3"> ... </div>

Symptom

I encountered an REXML Error of

Last 80 unconsumed characters

when parsing utf-8 xml strings using REXML on Ruby1.9.1.

Solution

try check encoding

puts xmlstring.encoding #=> 'US-ASCII' in my case

If the return value is not “utf-8″, you can change the encoding as below.

xmlstring.force_encoding("utf-8")

By this change, REXML will parse the input with the correct encodings.
