(CSS is for programming, not for pasting.)

When the Closure Tools were first released a little over two years ago, they gave web developers the ability to organize and optimize their JavaScript and HTML in a new way. But there was something missing, namely, a tool to help manage CSS.

You see, the nature of CSS runs contrary to the DRY principle that is exhibited in good software engineering. For example, if there is a color that should be used for multiple classes in a stylesheet, a developer has no choice but to copy-and-paste it everywhere because CSS has no concept of variables. Similarly, if there is a value in a stylesheet that is derived from other values, there is no way to express that because CSS also lacks functions. Common patterns of style blocks are duplicated over and over because CSS has no macros. All of these properties of CSS conspire to make stylesheets extremely difficult to maintain.

To this end, we are excited to introduce the missing piece in the Closure Tools suite: Closure Stylesheets. Closure Stylesheets is an an extension to CSS that adds variables, functions, conditionals, and mixins to standard CSS. The tool also supports minification, linting, RTL flipping, and CSS class renaming. As the existing Closure Tools have done for JavaScript and HTML, Closure Stylesheets will help you write CSS in a maintainable way, while also empowering you to deliver optimized code to your users. We hope you enjoy it! Please let us know what you think in the discussion forum.

Seo Master present to you: If you can select headgear for your LEGO ® action figures, your search engine should let you customize the theme for your search results page, right? Darn tooting!

True, Custom Search already lets you customize the look and feel of your search results page, but we're making it easier. You can now go to the control panel and select one of the predefined themes that broadly matches the look and feel of your website.

If the standard themes are not quite what you want, you can make further changes. You can tinker with the page layout (Why stick with a single column of results, when you can have two?) and play with the font colors and types. The standard themes paired with the "Compact" layout option are optimized for mobile devices, so they work well on iPhone, Android devices, and Pre.

If you want a greater level of control than that, you can download the CSS, tweak it in a text editor, and host the CSS in your website. You can make your search results page blend with the style of the rest of your website.

Seo Master present to you: On April 7th, Google launched a new version of Gmail for mobile for iPhone and Android-powered devices. We shared the behind-the-scenes story through this blog and decided to share more of what we've learned in a brief series of follow-up blog posts. This week, I'll talk about different ways to animate the floaty bar.

Even from the earliest brainstorming days for our new version of Gmail for iPhone and Android-powered devices, we knew we wanted to try something novel with menu actions: a context-sensitive, always-accessible UI element that follows conveniently as a user scrolls. Thus, the "floaty bar" was born! It took us a surprisingly long time, experimenting with different techniques and interactions, to converge on the design you see today. Let's look under the covers to see how the animation is achieved. You may be surprised to find that the logic is actually quite simple!


Screenshots of the floaty bar in action

In CSS:

.CSS_FLOATY_BAR {
 ...
 top: -50px;  /* start off the screen, so it slides in nicely */
 -webkit-transition: top 0.2s ease-out;
 ...
}

In JavaScript:

// Constructor for the floaty bar
gmail.FloatyBar = function() {
 this.menuDiv = document.createElement('div');
 this.menuDiv.className = CSS_FLOATY_BAR;
 ...
};

// Called when it's time for the floaty bar to move
gmail.FloatyBar.prototype.setTop = function() {
 this.menuDiv.style.top = window.scrollY + 'px';
};

// Called when the floaty bar menu is dismissed
gmail.FloatyBar.prototype.hideOffScreen = function() {
 this.menuDiv.style.top = '-50px';
};

gmail.floatyBar = new gmail.FloatyBar();

// Listen for scroll events on the top level window
window.onscroll = function() {
 ...
 gmail.floatyBar.setTop();
 ...
};

The essence here is that when the viewport scrolls, the floaty bar 'top' is set to the new viewport offset. The -webkit-transition rule specifies the animation parameters. (The 'top' property is to be animated, over 0.2s, using the ease-out timing function.) This is the animation behavior we had at launch, and it works just fine on Android and mobile Safari browsers.

However, there's actually a better way to achieve the same effect, and the improvement is particularly evident on mobile Safari. The trick is to use "CSS transforms". CSS transforms is a mechanism for applying different types of affine transformations to page elements, specified via CSS. We're going to use a simple one which is translateY. Here's the same logic, updated to use CSS transforms.

In CSS:

.CSS_FLOATY_BAR {
 ...
 top: -50px;  /* start off the screen, so it slides in nicely */
 -webkit-transition: -webkit-transform 0.2s ease-out;
 ...
}

In JavaScript:

// Called when it's time for the floaty bar to move
gmail.FloatyBar.prototype.setTop = function() {
 var translate = window.scrollY - (-50);
 this.menuDiv.style['-webkit-transform'] = 'translateY(' + translate + 'px)';
};

// Called when the floaty bar menu is dismissed
gmail.FloatyBar.prototype.hideOffScreen = function() {
 this.menuDiv.style['-webkit-transform'] = 'translateY(0px)';
};

Upon every scroll event, the floaty bar is translated vertically to the new viewport offset (modulo the offscreen offset which is important to the floaty bar's initial appearance). And, why exactly is this such an improvement? Even though the logic is equivalent, iPhone OS's implementation of CSS transforms is "performance enhanced", whilst our first iteration (animating the 'top' property) is performed by the OS in software. That's why the experience was unfortunately somewhat chunky at times, depending on the speed of the iPhone hardware.

You'll see smoother looking floaty bars coming very soon to an iPhone near you. This is just the first in a series of improvements we're planning for the mobile Gmail floaty bar. Watch for them in our iterative webapp, rolling out over the next couple of weeks and months!

Seo Master present to you: This is a very nice horizontal menu in which its sub-tabs are displayed in two columns and is also made with CSS, without any scripts.
The "advantage" so to speak, is that the sub-tabs when arranged in two columns are not very long, so it will be neat and less space along. You can see an example here:

Adding A Horizontal Menu With Sub Tabs in Two Columns To Blogger

STEP 1: In Blogger, go to your "Layout" and on the "Page Elements" section.

• Click on the "Add a Gadget" link just under your header image
• From the Gadget's List, select "HTML/JavaScript" option.

STEP 2: Simply copy and paste this ENTIRE code into your widget. Note: Leave the "Title" section of this widget blank.

<div id='menucol'>
<div id='topwrapper'>
<ul id='top'>
<li><a href='http://YOUR URL HERE.com'>Tab 1 Title Here</a></li>
<li><a href='http://YOUR URL HERE.com'>Tab 2 Title Here</a></li>
<li><a class='submenucol' href='#'>Tab 3 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.3</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.4</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.5</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.6</a></li>
</ul>
</li>
<li><a class='submenucol' href='#'>Tab 4 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.3</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.4</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.5</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.6</a></li>
</ul>
</li>
<li><a class='submenucol' href='#'>Tab 5 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.3</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.4</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.5</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.6</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.7</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.8</a></li>
</ul>
</li>
<li><a href='http://YOUR URL HERE.com'>Tab 6 Title Here</a></li>

</ul>
<br class='clearit'/>
</div>
</div>

Customize your main tabs by changing the Tab Titles to whatever you want. Include a URL for each one if you want it to be 'clickable'. If not, you can just put a # sign where it says http://YOUR URL HERE.com

You can add or delete as many of the main tabs as you need, just make sure to copy the entire code for the main tab for each additional tab you want:

<li><a href='http://YOUR URL HERE.com'>Tab 7 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 7.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 7.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 7.3</a></li>
</ul>
</li>

STEP 3: Now let's go a step further and add the CSS style in our Template

• Go to Template > Edit HTML

• Click on the sideways arrow next to <b:skin>...</b:skin> 

• Then click anywhere inside the code area and search - using CTRL + F keys - for the ]]></b:skin> tag and just above ]]></b:skin> add this code:

/* Horizontal menu with 2 columns
----------------------------------------------- */
#menucol {
width:940px;
height:37px;
background-image: -moz-linear-gradient(top, #666666, #000000);
background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0.00, #666666), color-stop(1.0, #000000));
filter: progid:DXImageTransform.Microsoft.Gradient(gradientType=0,startColorStr=#666666,endColorStr=#000000);
border-bottom:1px solid #666666;
border-top:1px solid #666666;
margin:0 auto;padding:0 auto;
overflow:hidden;
}
#topwrapper {
width:940px;
height:40px;
margin:0 auto;
padding:0 auto;
}
.clearit {
clear: both;
height: 0;
line-height: 0.0;
font-size: 0;
}
#top {
width:100%;
}
#top, #top ul {
padding: 0;
margin: 0;
list-style: none;
}
#top a {
border-right:1px solid #333333;
text-align:left;
display: block;
text-decoration: none;
padding:10px 12px 11px;
font:bold 14px Arial;
text-transform:none;
color:#eee;
}
#top a:hover {
background:#000000;
color:#F6F6F6;
}
#top a.submenucol {
background-image: url(http://www.matrixar.com/-TkveEnZCoIw/Uat7PEv8kBI/AAAAAAAADsY/iqVPPTJzvUs/s1600/arrow_white.gif);
background-repeat: no-repeat;
padding: 10px 24px 11px 12px;
background-position: right center;
}
#top li {
float: left;
position: relative;
}
#top li {
position: static !important;
width: auto;
}
#top li ul, #top ul li {
width:300px;
}
#top ul li a {
text-align:left;
padding: 6px 15px;
font-size:13px;
font-weight:normal;
text-transform:none;
font-family:Arial, sans-serif;
border:none;
}
#top li ul {
z-index:100;
position: absolute;
display: none;
background-color:#F1F1F1;
margin-left:-80px;
padding:10px 0;
border-radius: 0px 0px 6px 6px;
box-shadow:0 2px 2px rgba(0,0,0,0.6);
filter:alpha(opacity=87);
opacity:.87;
}
#top li ul li {
width:150px;
float:left;
margin:0;
padding:0;
}
#top li:hover ul, #top li.hvr ul {
display: block;
}
#top li:hover ul a, #top li.hvr ul a {
color:#333;
background-color:transparent;
text-decoration:none;
}
#top ul a:hover {
text-decoration:underline!important;
color:#444444 !important;
}

• Now find (CTRL + F) this line:

/* Tabs

• It will also have some little lines beneath:

/* Tabs
----------------------------------------------- */

• And just below these little lines, delete the code below until you reach at:

/* Columns
----------------------------------------------- */

• Instead of the code that you have removed, add this one:

#crosscol ul {z-index: 200; padding:0 !important;}
#crosscol li:hover {position:relative;}
#crosscol ul li {padding:0 !important;}
.tabs-outer {z-index:1;}
.tabs-inner {padding: 0 0px;}

STEP 4: The final step is to Save the Template and you are done!
