max-width:100% not working on images in mozilla

Question

I am designing a responsive website for a client where the image needs to be resized according to the width of screen. I set the image to max-width:100% and height:auto and it's working perfectly in chrome but not in mozilla.

Here is the link http://touchtalent.cloudvent.net/

Also, there is a similar question at Image mysteriously ignoring max-width in Firefox & IE

And, according to it's answer, I tried to give it's parent a width of 100%, but that doesn't help.

Here is my HTML code

<div id="wrapper">
   <header>
        <section class="banner1">
            <img class="banner" src="img/banner1.jpg" alt="banner1"/>
            <div class="tag1">
            BECAUSE YOU HAVE 
            </div>
        </section>
        <section class="banner2">
            <img class="banner" src="img/banner2.jpg" alt="banner2"/>
        </section>
        <section class="banner3">
            <img class="banner" src="img/banner3.jpg" alt="banner3"/>
            <div class="tag2">
            A 
            </div>
            <div class="tag3">
            CREATIVE GENIUS
            </div>
            <div class="tag4">
            INSIDE YOU
            </div>
            <div class="tag5">
                <div class="btn_join">
                JOIN US 
                </div>
            </div>
        </section>
   </header>
</div><!--wrapper-->

Here is its CSS

Please help!

Answer 1

For my issue (and using a bootstrap derivative), I didn't want my images scaled to 100% when they weren't intended to be as large as the container.

For my xs container (<768px as .container), not having a fixed width drove the issue, so I put one back on to it with javascript & jQuery (less the 15px col padding).

// Helps bootstrap 3.0 keep images constrained to container width when width isn't set a fixed value (below 768px), while avoiding all images at 100% width.
// NOTE: proper function relies on there being no inline styling on the element being given a defined width ( '.container'  )

function setWidth() {
    width_val = $( window ).width();
    if( width_val < 768 ) {
        $( '.container' ).width( width_val - 30 );
    } else {
        $( '.container' ).removeAttr( 'style' );
    }
}

setWidth();
$( window ).resize( setWidth );

I had the same problem and after reading this bugzilla report https://bugzilla.mozilla.org/show_bug.cgi?id=975632 I found out that if the image is nested in a table or a {display: table;} property is applied, then the max-width trick doesn't work because the table adapts to its content size.

So I hunted down this property in my DOM via dev tools in Firefox and I found a {display: table;} on one of the very first divs. Some attempt to scale the website ? I'm using currently TikiWiki CMS, an old version (12).

Anyway, correcting the CSS to {display: block;} made the {max-width: 100%} rule now work, and so finally I get the small images keeping their sizes and the big ones resizing to the container width.

As it took me some time to find out, I just thought let's share this if it can avoid others to loose time on this !!!

Answer 3

You must use image width="100%" like (). It must work for you. Gud Luck

Answer 4

You have float:left applied to all elements. Floated blocks occupy as much width, as needed by their content. In this case, image initial width "spreads" on the parent section.

And max-width on replaced block elements (such as images) doesn't make them occupy all the space - it just makes them not to widen more, than soe value. width:100% does

Try removing the float rule and give images width:100%

Answer 5

This is completly working, however, you set a minimum width on your #wrapper div content. Remove it from the main.css line 550 and it will work

CSS

#wrapper {
width: 100%;
/* min-width: 1000px; to remove */
overflow: hidden;
}

Answer 6

add this to your css

  body, html {margin: 0; padding:0; width: 100%;min-width: 100%;max-width: 100%;}

  img.banner {
    width: 100%;
    min-width: 100%;
    max-width: 100%;
    height: auto;
    display: block;
  }
 .banner1, .banner2, .banner3 {
    width: 100%;
    min-width: 100%;
    max-width: 100%;
    position: relative;
  }

also as also mentioned remove the float?

    * {float: left;}

Answer 7

Add this to your css.

body {width: 100%;)

Your elements are displaying as 100% of your parent element. Webkit renders this properly, but Chrome requires you to explicitly state the width of your body to achieve the proper result.
