CSS classes selecter [class*=“span”] [class^="classname"][class$="classname"]

CSS classes selecter [class*=“span”] [class^="classname"][class$="classname"] examples below;

.show-grid [class*="span"] {
    background-color: #eee;
    text-align: center;
    border-radius: 3px;
    min-height: 30px;
    line-height: 30px;
}

It's an attribute wildcard selector. In the sample you've given, it looks for any child element under.show-grid that has a class that CONTAINS span.

So would select the  element in this example:

< div class="show-grid">
     class="span6">Blah blah
< /div>

You can also do searches for 'begins with...'

div[class^="something"] { }

which would work on something like this:-

< div class="something-else-class">< /div>

and 'ends with...'

div[class$="something"] { }

which would work on

< div class="you-are-something">< /div>

Reminiscence always leftovers

Why someone can do such a silly mistake 
by making away with oneself...

Why the other side of the surrounding couldn't be seen, 
though family and friend always there for good and either. 

Difficulties ever opted to be allotted for dissolution 
and none would be misfortunates. 

Certainly, it can't be unfasten, 
nevertheless reminiscence always leftovers. 

Alas! overwhelming compassion to those ones... :-(
