html - Optimise CSS Delivery in Wordpress Theme -


when using page speed insights alert

eliminate render-blocking javascript , css in above-the-fold content page has 1 blocking css resources. causes delay in rendering      page. approximately 3% of above-the-fold content on page    rendered without waiting following resources load. try defer or   asynchronously load blocking resources, or inline critical portions of   resources directly in html. optimize css delivery of following: http://www.mysite.co.uk/wp-content/themes/mytheme/css/m.min.css

note: removed url working site workplace.

i have tried doing suggested google , using 

<script>   var cb = function() {     var l = document.createelement('link'); l.rel = 'stylesheet';     l.href = 'small.css';     var h = document.getelementsbytagname('head')[0]; h.parentnode.insertbefore(l, h);   };   var raf = requestanimationframe || mozrequestanimationframe ||       webkitrequestanimationframe || msrequestanimationframe;   if (raf) raf(cb);   else window.addeventlistener('load', cb); </script>

but did not solve problem. have tried removing css link told me remove js files , font awesome files well.

i @ 97/100 on page speed insights appreciate help.

the best way eliminate render blocking css extract "above fold" or "critical" css required render page , inline html. there can asynchronously load remaining css required load rest of page.

the idea behind of resources need in 1 roundtrip server html page. remaining or "non-critical" resources, load asynchronously. more details, see this article on google developers website.

i find best tool use extract critical css grunt plugin called grunt-critical. if you've never used grunt before wordpress, there great tutorial on tuts+ site walk through it.

apart that, can asynchronously load javascript using html async attribute.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
