css - My site's fluid grid not working in IE11 -


i've created site via dreamweaver, , it's supposed responsive. when tested in chrome , firefox, it's working fine, when tested in ie11, it's not working expected. reason, ie11 having trouble adjusting text. layout sort of this:

there's parent div 2 child divs (one image , text). depending on row position, image either on right or left , set take 50% of width.

the max width of grid container 1280px , each image, exception of banner 640 x 800.

i've left fluid grid css default (in dreamweaver). i've made 2 versions of page (index , index2) , both have same problem.

here's div in index

        <div class="over480">  			<!-- technology section -->         	  <div class="divhomecontent" id="fhtech">              	<div class="hcimg1">                  	<a href="tech.html"><img src="images/thumbs/tech_btn.jpg" alt="" border="0"/></a>                  </div>                  <div class="hctxt1">                  	<span class="spncont">developing next generation products control systems , power supply</span>                  </div>              </div>              <!-- end technology section -->                            <!-- project engineering section -->         	  <div class="divhomecontent" id="fhpe">                  <div class="hctxt2">                  	delivering world-class engineering solutions through power generation expertise.                  </div>              	<div class="hcimg2">                  	<a href="pe.html"><img src="images/thumbs/pe_btn.jpg" alt="" border="0"/></a>                  </div>                                  </div>              <!-- end project engineering section -->                            <!-- marketing & sales support section -->            <div class="divhomecontent" id="fhmkt">              	<div class="hcimg1">                  	<a href="mkt.html"><img src="images/thumbs/ms_btn.jpg" alt="" border="0"/></a>                  </div>                  <div class="hctxt1">                  	enhancing product awareness across region , sales win through effective customer engagement.                  </div>              </div>              <!-- end marketing & sales support section -->                            <!-- supply chain section -->            <div class="divhomecontent" id="fhsc">                  <div class="hctxt2">                  	the control tower - ensuring delivery of products whenever , wherever customers need them.                  </div>              	<div class="hcimg2">                  	<a href="sc.html"><img src="images/thumbs/sc_btn.jpg" alt="" border="0"/></a>                  </div>                                  </div>              <!-- end supply chain section -->                            <!-- lifecycle services section -->            <div class="divhomecontent" id="fhls">              	<div class="hcimg1">                  	<a href="ls.html"><img src="images/thumbs/ls_btn.jpg" alt="" border="0"/></a>                  </div>                  <div class="hctxt1">                  	best-in-class technical support , services solve our customers&rsquo; toughest problems.                  </div>              </div>              <!-- end lifecycle services section -->

in firefox , chrome, responsive design working expected: texts vertically align, , word wrap adjusts great, 2 child divs side-by-side.

however in ie11, texts remain vertically @ top , divs text part on left don't seem wrap text , seem go beyond max width set. result, right-had div, houses image, goes bottom.

please :(

i can see you're using flexbox displays, has been known have issues ie11 (and internet explorer in general)

i suggest, if want browser support - utilize grid system such bootstrap or alternatively if wanted more light weight, go toast grid

you can check browser compatibility using website called caniuse - it's handy checking cross-browser compatibility , provides alternative resources can use!
