using bootstrap 3.
I have 4 img elements.
2 images across 2 images down
Total of 4 images.
This is my markup:
<html> <body> <div class="row" id="row1"> <div class="col-xs-6"> <img src="" id="img1" class="img-responsive" alt="" /> </div> <div class="col-xs-6"> <img src="" id="img2" class="img-responsive" alt="" /> </div> </div> <div class="row" id="Div1"> <div class="col-xs-6"> <img src="" id="img3" class="img-responsive" alt="" /> </div> <div class="col-xs-6"> <img src="" id="img4" class="img-responsive" alt="" /> </div> </div> </body> </html> Trouble is that there is a gap in the middle. When I view the element using Chrome there are no margins or paddings automatically set by Bootstrap.
What should I do/use?
This is the screenshot (this is a mobile browser)
