HTML uses color whereas SVG uses fill and stroke. You can get fill or stroke to use the value of the color CSS property by using the value `currentColor` e.g. `fill=&quot;currentColor&quot;`

You can use `fill=&quot;currentColor&quot;`.

    &lt;a href=&quot;#&quot; style=&quot;color:red&quot;&gt;
    &lt;svg fill=&quot;currentColor&quot;&gt; ...&lt;/svg&gt;
    &lt;/a&gt;

stroke=&quot;currentColor&quot; this worked for me

Define the `fill:` of the whole SVG as `currentColor` in the CSS:
```
svg {
  fill: currentColor;
}
```
This makes the whole SVG to inherit the normal CSS `color:` of the surrounding element. Just make sure that all SVG child elements don&#39;t have any `fill` defined.

I have to count all the values in a matrix (2-d array) that are less than 200.

The code I wrote down for this is:

    za=0   
	p31 = numpy.asarray(o31)   
	for i in range(o31.size[0]):   
		for j in range(o32.size[1]):   
			if p31[i,j]&lt;200:   
				za=za+1   
	print za

`o31` is an image and I am converting it into a matrix and then finding the values.

Is there a simpler way to do this?

I have a bunch of SVG images that I want to embed in an HTML page, which is styled with CSS.

I want to be able to have elements in the SVG have their color inherited from the parent HTML element&#39;s color attribute.

I tried setting `style=&quot;stroke: none; fill: inherit&quot;` but this doesn&#39;t work.

My company writes software that installs on client machines to perform point-of-sale transactions.  The software interfaces with a variety of external peripherals (receipt printers, bar code scanners, credit-card readers, etc). We do this with a WinForms app that we created in Visual Studio using the Microsoft OPOS library, which in turn communicates with our cloud server.

There are obvious inefficiencies in this model, primarily with updates.  I&#39;m researching other ways to communicate with these peripherals over the web, preferably via web browser. So far as I can tell, Java is one of the only technologies out there that can do what we&#39;re looking for (via applet), and I assume Adobe Flash can as well (via the Air platform).  These are viable, but not preferable because we want to run our software on web-enabled mobile devices.

Does anybody have suggestions for other ways to communicate with external peripherals over the web?

Can HTML5 communicate with peripherals like scanners and credit card readers?

HTML5 websockets currently use a form of TCP communication. However, for real-time games, TCP just won&#39;t cut it (and is great reason to use some other platform, like native). As I probably need UDP to continue a project, I&#39;d like to know if the specs for HTML6 or whatever will support UDP?


Also, are there any reliable benchmarks for WebSockets that would compare the WS protocol to a  low-level, direct socket protocol?

When I render a highcharts-chart to a div container, how can I get access to the chart object through the div-Container?

I don&#39;t want to make the chart variable global.

    		var chart = new Highcharts.Chart({
    			chart: {
    				renderTo: &quot;testDivId&quot;,
                                    ...

I want to access the chart outside of the context above like this (pseudocode), to call functions:

    var chart = Highcharts.Chart(&quot;testDivId&quot;); //access from id
    chart.redraw();

How can I get access to a Highcharts chart through a DOM-Container?

During my random testing I saw a behavior where I put an anchor tag inside another anchor tag. I made a [jsfiddle][1].

    &lt;a class=&quot;groupPopper&quot;&gt;
         &lt;a class=&quot;name&quot;&gt; content&lt;/a&gt;
    &lt;/a&gt;​

But in the developer tool it appears different:

![enter image description here][2]


I believe we cannot put an anchor tag inside another anchor tag as  clicking on the inner anchor will bubble up the click event to the parent anchor tag which should not be allowed.

Is my assumption correct?

I&#39;m trying to have an ellipsis animate, and was wondering if it was possible with CSS animations...

So it might be like

And basically just continue like that. Any ideas?

I have a CSS Animation for a div that slides in after a set amount of time. What I would like is for a few divs to fill the space of the animated div that slides in, which it will then push those elements down the page. 

When I attempt this at first div that slides in still takes up space even when it is not visible. If I change the div to `display:none` the div doesn&#39;t slide in at all. 

How do I have a div not take up space until it is timed to come in (using CSS for the timing.)

I am using Animate.css for the animations.

Here is what the code looks like: 


    &lt;div id=&quot;main-div&quot; class=&quot;animated fadeInDownBig&quot;&gt;&lt;!-- Content --&gt;&lt;/div&gt;

    &lt;div id=&quot;div1&quot;&gt;&lt;!-- Content --&gt;&lt;/div&gt;
    &lt;div id=&quot;div2&quot;&gt;&lt;!-- Content --&gt;&lt;/div&gt;
    &lt;div id=&quot;div3&quot;&gt;&lt;!-- Content --&gt;&lt;/div&gt;

As the code shows I would like the main div to be hidden and the other divs show at first. Then I have the following delay set: 

	#main-div{
	   -moz-animation-delay: 3.5s;
       -webkit-animation-delay: 3.5s;
       -o-animation-delay: 3.5s;
        animation-delay: 3.5s;
	}

It is at that point that I would like the main div to push the other divs down as it comes in. 

How do I do this?

Note: I have considered using jQuery to do this, however I prefer using strictly CSS as it is smoother and the timing is a bit better controlled. 

***EDIT***

I have attempted what Duopixel suggested but either I mis-understood and am not doing this correctly or it doesn&#39;t work. Here is the code: 

***HTML*** 

    &lt;div id=&quot;main-div&quot; class=&quot;animated fadeInDownBig&quot;&gt;&lt;!-- Content --&gt;&lt;/div&gt;

***CSS***

	#main-image{
		height: 0;
  		overflow: hidden;
	   -moz-animation-delay: 3.5s;
       -webkit-animation-delay: 3.5s;
       -o-animation-delay: 3.5s;
        animation-delay: 3.5s;
	}
	#main-image.fadeInDownBig{
		height: 375px;
	}

CSS Animation and Display None

I have a somewhat unusual issue. I&#39;ve done something like this many times:

    $(&#39;#selector&#39;).css(&#39;color&#39;,&#39;#00f&#39;);

My problem is that I create a `&lt;div id=&quot;selector&quot;&gt;`, and I call the command above and it works fine.

Now, on another event, later, I remove that element from the [DOM][1] and add it again at a later time with the same id. This element now doesn&#39;t have `color:#00f`.

Is there a way that I can add a rule in CSS, such that it will affect items that are created in the future with that same `id`/`class`? I like [jQuery][2], but anything with plain JavaScript would be fine as well.

It has to be dynamic, and I don&#39;t know the classes to put in a CSS file.  Also, I plan on changing a single attribute a few different times through the course of the application. For example, setting the `color` to `black`, to `blue`, to `red`, and back to `black`.

&lt;br/&gt;

&lt;hr/&gt;

I went with the answer from **@lucassp**, and this is what I ended up with:

    function toggleIcon(elem, classname)
    {
        if($(elem).attr(&#39;src&#39;)==&#39;img/checkbox_checked.gif&#39;)
        {
            $(elem).attr(&#39;src&#39;, &#39;img/checkbox_unchecked.gif&#39;)
            //$(&#39;.&#39;+classname).hide();//this was the old line that I removed
            $(&#39;html &gt; head&#39;).append($(&#39;&lt;style&gt;.&#39;+classname+&#39; { display:none; }&lt;/style&gt;&#39;));
        }
        else
        {
            $(elem).attr(&#39;src&#39;, &#39;img/checkbox_checked.gif&#39;)
            //$(&#39;.&#39;+classname).show();//this was the old line that I removed
            $(&#39;html &gt; head&#39;).append($(&#39;&lt;style&gt;.&#39;+classname+&#39; { display:block; }&lt;/style&gt;&#39;));
        }
    }

I also want to say that **@Nelson** is probably the most &quot;correct&quot;, though it would require more work to go into application code that always works fine, and that&#39;s not effort I want to spend at the moment.

If I had to rewrite this (or write something similar) in the future, I would look into `detach()`.

I need help in taking right decision. I need to animate a background color of my user control when some event happens. When it is, I want to change the background just for 1 second and then turn it back. Which way should I go? Use color animation or timer or may by some other way.


Solved. Thanks to all! This works good for me:

            ColorAnimation animation;
            animation = new ColorAnimation();
            animation.From = Colors.Orange;
            animation.To = Colors.Gray;
            animation.Duration = new Duration(TimeSpan.FromSeconds(1));

I am fairly new to R and I have the following queries :

I am trying to generate a plot in R which has multiple lines (data series). Each of these lines is a category and I want it to have a unique color. 

Currently my code is setup in this way :

First, I am creating an empty plot :

    plot(1,type=&#39;n&#39;,xlim=c(1,10),ylim=c(0,max_y),xlab=&#39;ID&#39;, ylab=&#39;Frequency&#39;)

Then for each of my category, I am plotting lines in this empty plot using a &quot;for&quot; loop like so :

    for (category in categories){
    lines(data.frame.for.this.category, type=&#39;o&#39;, col=sample(rainbow(10)), lwd=2)
    }

There are 8 categories here, and so there are 8 lines produced in the plot. As you can see, I am trying to sample a color from the rainbows() function to generate a color for each line. 

However, when the plot is generated, I find that there are multiple lines which have the same color. For instance, 3 of those 8 lines have green color. 

How do I make each of these 8 lines have a unique color ? 

Also, how do I reflect this uniqueness in the legend of the plot ? I was trying to lookup the `legend()` function, however it was not clear which parameter I should use to reflect this unique color for each category ? 

Any help or suggestions would be much appreciated.

The `input type=&quot;color&quot;` has a default color which is black: `#000000`.

Even if I give it an empty value...

`&lt;input type=&quot;color&quot; value=&quot;&quot; /&gt;`

...the default color is always black.

I want the user to have the option of picking a color, but if he doesn&#39;t it means no color was picked, not even white `#FFFFFF`.

Is there a way to force an `input type=&quot;color&quot;` not to have black color as default?

I can use some kind of a &quot;listener&quot; to check if the user changed the color for the first time, if not, ignore the value, but I would like to avoid Javascript.

How would I fill an SVG shape, not with a single colour, an image or a gradient, but with a hatching pattern, diagonal if possible.

It&#39;s been 2 hours and I&#39;ve found nothing (at least after 2005).

I figure a possible hack would be a hatched PNG that would serve as fill, but that is not ideal.

I&#39;m looking to use an SVG logo for a website — to make it look great on a responsive design for all devices. 

But since [there are issues][1], I want to support as many devices and browsers as possible. Load speed is also an important consideration. How do export settings in Adobe Illustrator fit into all this?

In Illustrator, there are several options for SVG export. Firstly, **which SVG profile is best?**

![enter image description here][2]

I assume SVG Tiny has a lower file size? Do many devices support SVG Tiny? What are the most important differences? (Without having to read [this W3 monster][6].)

Secondly, I assume that the best option for image location is &quot;link&quot;? (See description after exclamation mark.)

![enter image description here][3]

Alternatively, how is browser support for the &quot;embed&quot; option?

![enter image description here][4]

Thank you!

&gt; P.S. There will be a fallback alpha-PNG option, but I want the SVG to
&gt; be supported as best as possible. (Come to think of it, a fallback
&gt; option — like a JPG — would probably be the best served in this case since alpha-PNG itself needs a solution for older IE.)

**Update:** There are also more options that can be configured. I am not working with text, so the only relevant one I see is the decimal places. For logos, something to be displayed as maximum 200x200px (so 400x400px on Retina displays), is &quot;3&quot; the best setting? Or &quot;2&quot; to minimize file size?

I&#39;m using D3 to generate a bar chart (I adapted the code from [this example](http://bl.ocks.org/3885304)). The labels I&#39;m using on the *x*-axis are a couple of words long each, and since this makes all of the labels overlap I need to break these labels across lines. (It&#39;ll be fine if I can replace all of the spaces in each label with newlines.)

I originally tried this by replacing the spaces with literal newlines (`&amp;#xA;`) and setting `xml:space=&quot;preserve&quot;` on the labels&#39; `&lt;text&gt;` elements. Unfortunately, it turns out that SVG doesn&#39;t respect this property. Next I tried to wrap each word in a `&lt;tspan&gt;` that I could later style. I passed each label through this function:

    function (text) {
        return &#39;&lt;tspan&gt;&#39; + text.replace(/ /g, &#39;&lt;/tspan&gt;&lt;tspan&gt;&#39;) + &#39;&lt;/tspan&gt;&#39;;
    }

but this just puts literal `&lt;tspan&gt;`s into the output. How can I wrap my text labels in `tspan`s (or do something else) so that my labels don&#39;t overlap?

How do I include newlines in labels in D3 charts?

Apple&#39;s iPad Mini is a smaller clone of the iPad 2 in more ways than we&#39;d want. In JavaScript, the `window.navigator` object exposes the same values for the Mini and iPad 2. My tests so far to detect the difference have not lead to success.

Why is this important? 

As the iPad Mini and iPad 2 screens are identical in pixels but vary in actual size (inches / centimeters), they vary in [PPI][1] (pixels per inch).

For web applications and games to offer a friendly user interface, certain elements are adjusted in size relative to a user&#39;s thumb or finger position, thus, we may want to scale certain images or buttons to provide for that better user experience.

Things I have tried so far (including some pretty obvious approaches):

 - `window.devicepixelratio`
 - CSS element width in cm unit
 - CSS media queries (such as `resolution` and `-webkit-device-pixel-ratio`)
 - SVG drawings in similar units
 - Doing all sorts of CSS webkit transforms for a set time and counting rendered frames with `requestAnimFrame` (I was hoping to detect a measurable difference)

I&#39;m fresh out of ideas. How about you?

**Update**
Thanks for the responses so far. I would like to comment on people voting against detecting iPad mini versus 2 as Apple has uhm, one guideline to rule them all. Okay, here&#39;s my reasoning why I feel it really makes all sense in the world to know if a person is using an iPad mini or a 2. And do with my reasoning what you like.

The iPad mini is not only a much smaller device (9.7 inch versus 7.9 inch), but its form factor allows for a different usage. The iPad 2 is usually held with two hands when gaming unless you&#39;re [Chuck Norris][2]. The mini is smaller, but it is also much lighter and allows for gameplay where you hold it in one hand and use another to swipe or tap or whatnot. As a game designer and developer myself, I&#39;d just like to **know** if it&#39;s a mini so I can choose to provide the player with a different controlscheme if I want (for instance after A/B testing with a group of players). 

Why? Well, it&#39;s a proven fact that the majority of users tend to go with the default settings, so leaving out a virtual thumbstick and putting some other tap-based control on the screen (just giving an arbitrary example here) when the player loads up the game for the first time is what I, and probably other game designers, would love to **be able to** do.

So IMHO this goes beyond the thick fingers / guidelines discussions and is just something Apple and all other vendors ought to do: allow us to uniquely identify your device and **think different** instead of **following** guidelines.
