html - 100% width in three-column layers? -

-

having html:

<div class="images_portfolio panel-widget-style"> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> <a href="imagelink"><img src="x.jpg" alt="" /></a> </div>

and css:

.images_portfolio.panel-widget-style img {     width:100%;     height:auto; }  .images_portfolio.panel-widget-style {     position:relative;     display:block;width:32%;margin-right:1%;     float:left;     margin-bottom:1%; }

it

i can 32%+32%+32% = 96% + margin right (1%*3) = 99% in total of parent element.

how can 100% of parent element works in major browsers? number of links can vary never know if it's 5 or 18 etc... (i want the images aligned element down below 100%. hope understand mean).

try using width: 33,33333333% , instead of margin-right use padding-right. padding offset inside element counts towards elements width.
