I have a vertical drop-down menu that is working fairly well. I have one bug that I cannot get a handle on, though.
You can find my menu here: test Page
The menu works fine in internet explorer (except for a little drop on the first submenu, that I can live with (bonus points if you know what that's about), but in other browsers, my background flows from the submenu back to the main menu. Where the "margin" is coming from?
so far I've found that it has something to do with how I've styled my li:hover children
Potentially useful snippets from my CSS
ul#menu3{
display:block;
left:20px;
margin:0;
width:10em;
padding:0;
position:absolute;
list-style:none;
}
ul#menu3 li{
color:#000000;/*
float:left;*/
position:relative;
margin:0;/*
margin-bottom:-1px;*/
line-height:31px;
text-align:center;
width:10em;
padding:0;
font-weight:bold;
display:block;
vertical-align:middle;
background-image:url(../../../menu4/awmdata/button-tile.gif);
}
ul#menu3 li:hover ul{
text-align:center;
vertical-align:bottom;
background-image:url(../../../menu4/awmdata/button-tile.gif);
background-repeat:repeat;
left:auto;
margin-top:-31px;
}
ul#menu3 li ul{
position:absolute;
left:-999em;
margin-left:10em;
margin-top:-31px;
}
ul#menu3 li ul li{
color:#000000;
margin:0;
left:auto;
padding:0;
font-weight:bold;
}
Stick this at the top of your styles.css
ul, li {
margin: 0;
padding: 0;
}
When using unordered lists for menu's it's always a good idea to remove the margin and padding so you have better control with your layout from the start

My footer and other container divs seem unaligned in iPhone Safari (it looks OK on Android):
Nothing had worked so far. What could be the cause?
CSS:
html,
body,
#wrapper {
height: 100%;
}
body > #wrapper {
height: 100%;
min-height: 100%;
}
#content {
clear: both;
padding-bottom: 36px;
}
#header,
#content,
#footer {
padding-left: 20px;
padding-right: 20px;
}
.container {
margin: 0 auto;
width: 960px;
}
#footer {
background: url(images/footer_bg.png) repeat-x 0 0;
margin: -65px 0 0;
padding: 15px 0 14px;
position: relative;
clear: both;
height: 36px;
}

You haven't really defined clear wrappers for your content sections, which makes this a bit harder to get everything to align. You could put some left padding on the left footer element if you wanted to move it over a bit, as it doesn't look great right up against the edge of the screen.
Anyhow, the section with the quote marks (top pink arrow in your image) is moved right by 4px because of the left margin of 4px on the latest-news div. You'll see the same thing by narrowing your desktop browser.
First I think it's the difference between the android and ios browser that will explain the difference between the browsers. Mobile browsers use zooming to fit a website to the device screen. Source: http://davidwalsh.name/zoom-mobile-browsers
<meta name="viewport" content="user-scalable = yes">
I think it's better to change it, so that the browser zooming is removed.
<meta name="viewport" content="width=device-width,initial-scale=1, maximum-scale=1">
Second: there is an extra css rule that overrides your .container:
.page-template-front-page-2-php .container {
width: 971px !important;
}
Maybe the css rule is forced to fit the screen.
The .container contains floating elements. De #content .container uses a overflow: hidden, but the #home-feed and #footer .containers doesn't have this declaration. The overflow: hidden will force the parent div to "see" that there is content inside. There are some disadvantages, but maybe it will do the trick.
Extra tip: why don't you use a css framework with a grid system like Twitterbootstrap, Foundation or Groundwork ?
I have a website (http://ukchina-trading.com/) with the following header:
HTML
<div class='leftImage'>
<img src='image/unionjack.png'>
</div>
<div class='title'>
<h1>J Plus Trading</h1>
<h2>Briding the gap between China and the UK</h2>
</div>
<div class='rightImage'>
<img src='image/chinawings.png'>
</div>
CSS
.title h1 {
font-family: 'Droid Serif', Georgia, Times, serif;
text-align: center;
font-size: 68px;
line-height: 65px;
padding-top: 60px;
margin-bottom: 80px;
}
.title h2 {
font-family: 'Droid Serif', Georgia, Times, serif;
text-align: center;
position:relative;
top:-88px;
left:3px;
font-size: 16px;
color: #FF3300;
}
.rightImage {
position:absolute;
right: 150px;
top: 2px;
}
.leftImage {
position:absolute;
left: 150px;
top: 2px;
}
When the website is view on a computer the header is fine, but when viewed on the iphone screen the images are pushed over the title, hiding it.
What is the best way to redo the header to stop this?
I'd suggest the best thing to do would be to bring the flags inside the 900px width of the website.
Keep them to the left and right of the "J Plus Trading" text but just use floats rather than absolute positioning.
your problem is the absolute positioning you are using, as this causes the images to be in the same position regardless of anything else on the page. instead of absolute try using float:left; and float:right on your left and right images, and this way the text will not be pushed over it. you may have to create extra containing divs with margins or padding so that the images are positioned how you want them
I have a css menu that works well in most desktop browsers, but I have had issues get my drop down menu to work on IPad and Iphone. Here is the site in question: http://bakersfield.kernhigh.org/
I am quite new to css and javascript, so any help would be great.
Thanks
Currently, iOS does not support :hover, so your navigation will not unfold in iOS as it does on a desktop.
Have you considered jQuery Mobile? I would only suggest that if you were developing a seperate mobile version, though.
Otherwise, you could use this jquery (you must also include jQuery then):
$('nav li').bind('touchstart', function(){
$(this).addClass('hover');
}).bind('touchend', function(){
$(this).removeClass('hover');
});
This will add a class (hover) upon the touch, and remove it upon removal of the finger.
You will of course have to edit this for your needs. I only say this because you say you are new to javascript and I don;t want to confuse you.
Drop down menus can suck, especially making them work with touch screen devices since you can't 'hover' on a touchscreen. This is how I do my drop down menus, it is pure CSS, and I have tested it on chrome, ff, ie7+, safari, iPhone and multiple Android (of course, you will want to tweak colors and sizing):
HTML
<div id="navigation">
<ul id="nav">
<li><a href="index.html>Home</a></li>
<li>Drop Down <!--Notice didn't close the li yet->
<ul>
<li>Drop Down Item</li>
<li...../li>
etc...
</ul>
</li>
<li>Another Drop Down</li>
<ul>
...
</ul
</li>
</ul>
</div>
CSS:
#nav {
display: block;
text-align: center;
font-size: 1em;
position: relative;
height: 3em;
width: 950px;
margin-right: auto;
margin-left: auto;
list-style-type: none;
}
#nav li {
float: left;
display: block;
width: 75px;
height: 3em;
position: relative;
}
#nav li a {
text-decoration: none;
display: block;
height: 1em;
padding-top: 1em;
padding-bottom: 1em;
}
#nav li a:hover {
color: #990000;
background-color: #999999;
}
#nav li ul {
width: 100%;
display: none;
z-index: 9999;
position: absolute;
}
#nav li ul li {
display: block;
clear: both;
width: 100%;
height: 100%;
background-color: #B5BDC8;
}
#nav li:hover ul {
display: block;
}
The idea behind all of this is to create a list, then inside that other lists to create the drop down elements....
Then, from there, display only the primary list items to begin with, then show the drop down menu on hover (or in the case of a mobile device on click by making the main list item a link to "#" thus creating and active/hover state)...
The only issue is that by using display:none it isn't screen reader friendly, however I always include site navigation at the bottom that is screen reader friendly, and SEO friendly as well.
You can see an example of this in action on this website I am working on here
In general, drop down menu's such as this usually aren't good practice to have for mobile sites. This is because you can't really hover over a navigation item with your finger, and pressing an item could prove difficult without zooming in on the menu.
A solution is having different CSS styles for your navigation when being viewed on a mobile device. Here is a great resource for helping you convert your navigation to be more mobile friendly:

I've styled an ordinary link to resemble a button in our Sencha Touch 2-based mobile application, and I'm having issues with most of the link not functioning in Safari on the iPhone.
The link is an ordinary <a> tag with an inner <span> element containing the label text. There is padding on the <a> element, which allows taps to be registered. It appears that the inner <span> is blocking taps from being registered in the parent anchor as a link tap, and its background is transparent.
Here's the markup:
<a href="http://test-site.xx/full-site-page?param=value" class="x-button-normal x-button btn-profile">
<span class="x-button-label">View profile on full site</span>
</a>
Testing this in Chrome doesn't present any problems, i.e. clicking the span causes the parent hyperlink to be followed. Both are Webkit-based browsers. One of our testers also tested this in Safari on a Macbook with no problems; I have also tested this in Chrome using a Wacom Bamboo tablet with no problems. This is only an issue on mobile devices (tested on both iPhone and Android 2.2) - which is what we're targeting.
Is there a CSS property I can set on the <span> element to allow taps to fall through to the parent hyperlink? Ideally I want to avoid having to set events through JavaScript. Any ideas as to why this isn't working as I'd expect?
Update: Here are the styles for the inner span as reported by Chrome's developer console:
-webkit-box-align: center;
-webkit-box-flex: 1;
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
-webkit-user-drag: none;
-webkit-user-select: none;
background-attachment: scroll;
background-clip: border-box;
background-color: transparent;
background-image: none;
background-origin: padding-box;
border-bottom-color: white;
border-bottom-style: none;
border-bottom-width: 0px;
border-left-color: white;
border-left-style: none;
border-left-width: 0px;
border-right-color: white;
border-right-style: none;
border-right-width: 0px;
border-top-color: white;
border-top-style: none;
border-top-width: 0px;
box-shadow: none;
box-sizing: border-box;
color: white;
cursor: auto;
display: inline;
font-family: 'Helvetica Neue', HelveticaNeue, Helvetica-Neue, Helvetica, 'BBAlpha Sans', sans-serif;
font-size: 18px;
font-weight: bold;
height: auto;
line-height: 21px;
overflow-x: hidden;
overflow-y: hidden;
padding-bottom: 0px;
padding-left: 0px;
padding-right: 0px;
padding-top: 0px;
position: static;
text-align: center;
text-decoration: none;
text-overflow: ellipsis;
white-space: nowrap;
width: auto;
Many thanks.
Solved it, thanks to this post which mentions the following CSS property:
pointer-events: none;
Adding this to the style for the inner <span> (and inner floated <img> as alluded to in my second comment) allowed these to pass the tap through to the parent hyperlink.
The strange thing is that Sencha Touch 2 seemed to interfere with the DOM, not sure what it was in particular. Mocking up a similarly-styled button on a completely static HTML page (no JavaScript, let alone Sencha Touch 2) did not exhibit the original problem on a mobile device.
Another option in the simple case (single <span>, no floated images) was to refactor the styles to eliminate the need for an inner <span>, though this wasn't feasible for the more complicated case:
<a class="attachment" href="/someRepository/someDownload.pdf">
<img src="/images/fileExtension-pdf.png" alt="Attachment"/>
<span class="title">Title of download</span>
<span class="size">xxx kB</span>
</a>
I think this has to do with Sencha Touch's prevention of zooming. They have added in code to preventDefault most touchstart events (which kill the use of the link). There is an exception for anchors, but not for children of anchors (so tapping on an anchor itself works fine, but not tapping on a span within an anchor). I was able to monkey patch a quickfix in my application launch method:
Ext.Viewport.setPreventZooming(false); // unbind any existing handler
Ext.Viewport.doPreventZooming = Ext.Function.createInterceptor(Ext.Viewport.doPreventZooming, function(e){
return !Ext.fly(e.target).findParent('a');
});
Ext.Viewport.setPreventZooming(true);
The above code comes with no warranties (have not tested on Android and I suspect it to be fairly inefficient). I have also reported this as a bug: http://www.sencha.com/forum/showthread.php?215032-Links-are-prevented-when-tapping-on-children
I'm trying to make this website: http://501commons.org render the same on iPhone as on other browsers. On Android it works just fine. I have already added the -webkit-text-size-adjust: 100%; to the body style, which helped a little. What is still not working are the following pieces, and I can't figure out why mobile safari is not displaying them properly:
the top left logo just plain won't show up
the search box in the top right is way too far to the left
the red slogan in the header "A Resource for Nonprofits etc" is too large, too low, and extends beyond the right border
the font of the three nav menu items (Explore the Commons, Volunteer, Invest) is too large
Everything else seems ok, at least on the home page. What's weird is that all four problems above occur in the header.
Any help would be hugely appreciated!
Thanks!
I figured it out:
Top left logo
The logo not showing up was due to a strange non-cascading issue. The logo is an <img> tab inside an <a id="portal-logo" ...>. The #portal-logo has a display: inline-block; rule in the next-to-last stylesheet that applies to it, but not in the last one. In other words, this is what we have:
#portal-logo { /* in the last CSS file */
margin-bottom: 0;
}
#portal-logo { /* in the next-to-last CSS file */
display: inline-block;
margin: 1.375em 0;
}
Adding display: inline-block; to the last stylesheet magically makes the logo appear. Then I had to also fiddle with margins, position, top, etc to make it appear in the right place, but all these are in a CSS file that is loaded conditionally only on mobile browsers, so it's ok. It's just really strange that Safari on iOS does not cascade the display: inline-block; style!
Search box
I made the search box be rendered in the proper place by adding text-align:right; to its container, even though an earlier rule for the same container with text-align:left; makes it work just fine in every other browser.
Slogan
The slogan required the most tweaking. It's contained in a <div id="slogan">. Here is the old rule:
#slogan {
color: #EE3524;
float: right;
font-size: 110%;
font-weight: bold;
margin-right: -190px;
padding-top: 60px;
position: relative;
z-index: 1;
}
And here is the new rule that works on mobile safari:
#slogan {
-webkit-text-size-adjust: 100%;
clear:right;
color:#ee3524;
font-size:17.6px;
font-weight: bold;
float:right;
margin-right:0px;
padding-bottom:50px;
padding-top:0px;
position:relative;
text-align:right;
z-index:1;
}
One of the key differences is the absolute font-size in px, instead of as a % value.
Menu Items font
Likewise, specifying the font-size in px instead of % seemed to be the key here:
Old:
#portal-globalnav li a {
background-color: transparent;
color: #FFFFFF;
font-size: 1.2em;
font-weight: bold;
min-width: 3em;
padding-bottom: 11px;
}
New:
#portal-globalnav li a {
background-color:transparent;
color:#fff;
font-size:15.4px;
font-weight:bold;
padding-bottom:11px;
min-width:3em;
}
YMMV!
