css - Progressive Enhancement with box-shadow -

-

i use webkit's box-shadow css property little drop-down. code like:

.drop_down{   -webkit-box-shadow: 1px 1px 4px #888;   box-shadow: 1px 1px 4px #888; }

however, browsers not have capability, use borders approximate drop shadow, so:

.drop_down{   border-top: 1px solid #bbb;   border-left: 1px solid #bbb;   border-right: 2px solid #bbb;   border-bottom: 2px solid #bbb; }

the problem is, don't want border-based shadow show browsers support box-shadow. avoid browser sniffing because assume it's hard cover cases. simplest way this? prefer javascript-less solution, consider simple javascript-based ones too.

modernizr feature detection. code be:

.drop_down{   border-top: 1px solid #bbb;   border-left: 1px solid #bbb;   border-right: 2px solid #bbb;   border-bottom: 2px solid #bbb; } .boxshadow .drop_down{   border: 0px none;   -webkit-box-shadow: 1px 1px 4px #888;   box-shadow: 1px 1px 4px #888; }

you need include modernizr javascript library work.

a colleague of mine designing sql queries 1 below produce reports, displayed in excel files through external data query. @ present, reporting processes on db required (no crud operations). i trying convince him better use ruby orm in order able display data in rails/sinatra app. despite obvious advantages in displaying data, advantages there him in learning use orm sequel or datamapper? the sql queries writing quite complex, , being relatively new sql, complains time-consuming , confusing. possible write extremely complex queries orm? , if so, suitable(i have heard sequel legacy dbs)? , advantages of learning ruby , using orm versus sticking plain sql, in making complex database queries? i'm datamapper maintainer, , think complex reporting should use sql. while think someday we'll have dsl provides power , conciseness of sql, i've seen far requires write more ruby code sql complex queries. rather maintain 5 line sql query 10-15 lines of ruby code desc...

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
