Lets fix the short comings of current CSS integrations – EQCSS / Element queries

“Element queries are a new way of thinking about responsive web design where the responsive conditions apply to elements on the page instead of the width or height of the browser.
Unlike CSS @media queries, @element Queries are aware of more than just the width and height of the browser, you can write responsive conditions for a number of different situations like how many characters of text or child elements an element contains.
Another concept that element queries brings to CSS is the idea of ‘scoping’ your styles to one element in the same way that JavaScript functions define a new scope for the variables they contain.”

Javascript Life Saver of the Week – uniqueID

Simple way to make sure you are assigning unique IDs to a series of elements.

var seedNum = 1;
function uniqueID(myKey, seedNum){
     var key = myKey + seedNum;
     if (document.getElementById(key) != null){
         return uniqueID(myKey, ++seedNum);
     }
     else{
         return key;
     }
 }

var seedNum = 1;

function uniqueID(myKey, seedNum){

var key = myKey + seedNum;

if (document.getElementById(key) != null){

return uniqueID(myKey, ++seedNum);

}

else{

return key;

}

USAGE

uniqueID('state-',seedNum);

1	uniqueID('state-',seedNum);

If you want to do IETF RFC-4122 compliant Universally Unique Identifiers (UUID), checkout Pure UUID.

Seems to be all about unique IDs this week ;)
