Is there a way for me to target SVG with CSS? They appear like broken images in IE8 downwards and I'd like to hide them using modernizr e.g. I was hoping for something like...
.no-svg object[type=svg] {
display:none;
}
I'm using this to embed SVG into my page as recommended in http://www.alistapart.com/articles/using-svg-for-flexible-scalable-and-fun-backgrounds-part-ii
<object type="image/svg+xml"
width="100" height="100" style="float:right"
data="http://blog.codedread.com/clipart/apple.svgz">
<span/></object>
The type attribute in your markup is image/svg+xml. Your attribute selector object[type=svg] looks for a type attribute which is exactly svg, so your object won't match.
You should specify the full MIME type as in your markup (you need the quotes here, or it won't work; see this spec for details):
.no-svg object[type="image/svg+xml"] {
display:none;
}
Or if you'd like you can use a substring attribute selector, but I prefer the above:
.no-svg object[type*=svg] {
display:none;
}

I'm importing an svg from file using the <object> element
<object data="img/icons/some-svg.svg" type="image/svg+xml"></object>
From the inspect element tool it's hierarchy appears as follows in the browser
<object data="img/icons/some-svg.svg" type="image/svg+xml">
#document
<svg ...>
...
</svg>
</object>
As I want to change the color of the svg how do I access the encapsulated svg component in the object element?
Here's how you insert a style into a document. The rect element has no colour defined in markup, the green colour comes from the javascript injected style rule.
document.styleSheets[0].insertRule('rect { fill: green; }', 0);
<svg viewBox="0 0 220 100" xmlns="http://www.w3.org/2000/svg"><rect width="100" height="100"/></svg>
So now we know how to do that how do we use it with an object tag. Well we need to get the object tag. You could either give it an id and get it by its id or try to find it in the DOM e.g.
let o = document.getElementsByTagName('object')[0];
Then you get its contentDocument i.e.
let doc = o.contentDocument;
and you can use that to insert the style as demonstrated above. I.e.
doc.styleSheets[0].insertRule('rect { fill: green; }', 0);
Unfortunately I can't demonstrate this from start to finish because the contentDocument of a data url is null.
svg {
fill: #ff0000;
}
use this css rule to change the color
I have a set of div whose visibility is set to either hidden or visible. Based on this css visibility property i need to add the css property on those div, like
<div class="div-class" style="color:#ff0000; margin: 0px 10px; visibility:hidden;">
[Block of Code]
</div>
Now i need to define the following in style.css file.
.div-class:visible {top:10px;left:50px;}
.div-class:hidden {top:0px;left:0px;}
Is this possible???
yes with css attributre selectors you can do it
try the below css:
.div-class[style*="visible"] {
color: green;
}
.div-class[style*="hidden"] {
color: red;
}
What you are trying to do is not "really" possible.
I mean it's ill thought by design in the first place.
Even Vamsikrishna's solution might not work as expected.
If you set the overflow property to hidden via javascript or inline styles, the .div-class[style*="hidden"] rule will apply since the style attribute will contain the hidden string.
Moreover , setting inline styles on html elements is bad practice itself in most cases.
I suggest you try and learn css principles a little more.
I'd do the following:
HTML
<div class="div-class div-hidden">
[Block of Code]
</div>
CSS
.div-class {color:#ff0000; margin: 0px 10px; top:10px;left:50px;}
.div-hidden {visibility:hidden;}
.div-class.div-hidden {top:0px;left:0px;}
Then you can use javascript to toggle the "div-hidden" class.
You can do something using attrchange - a jQuery plugin ,
like this:
Add "attrchange" script into HTML page like
In Javascrip catch event
var email_ver_input = $("input#email_ver_input.verifyInput");
email_ver_input.attrchange({
trackValues: true,
callback: function (event) {
if (email_ver_input.is(":visible")){
$("#inputcode_wrap").show();
}
}
});
I have this link :
</td>
and I want to change the image when the user over the link I tested :
#planification:hover{
background-image:"images_cartographie/cartographie3_03.gif";
}
but the image doesn't change, it is ignored, (I tested background-color it works (then the problem isn't in url or ...))
when I use the background-image without hover like that :
it doesn't appear :
#planification{
background-image:"images_cartographie/cartographie3_03.gif";
}
NB : I generated the page with photoshop
do you have any idea
You can completely remove the img because you add the efect via CSS on the a tag.
HTML
CSS
.image_link{
display:block;
width:800px;
height:600px;
background:url('http://ferringtonpost.com/wp-content/uploads/2012/07/Responsibilities-of-Owning-a-New-Puppy-Photo-by-bestdogsforkids.jpg');
}
.image_link:hover {
display:block;
width:800px;
height:600px;
background:url('http://25.media.tumblr.com/tumblr_m4frqhdW0k1rwpusuo1_1280.jpg');
}
JSFiddle.
Note that you must add dispay:block/inline-block to the a
I'm a little confused about your question, but it sounds like you need to put in two different images. So, there's one image when you mouse over, and another image when you don't. You just put in a different path for the background-url on hover. Also, you should put in a plank gif in your img tag for backwards compatibility.
You should also use a self closing tag /> for your image. The tag is open the way that you posted it.
#planification
{
background: url(images_cartographie/cartographie3_03.gif)
}
#planification:hover
{
background: url(images_cartographie/new_image_goes_here.gif)
}
<a id="planification" href = "" ><img src="images_cartographie/blank.gif" width="207" height="47" alt=""/></a>
I have a 2550px x 3300px image of a document. I scale it to 901px to 1166px using css. Also used image width/height attributes without css. It looks great in chrome and IE but the image contents look jagged in FF (3.6). Resizing the image itself is not an option (for good quality printing).
Any suggestions?
You could try adding the CSS tag image-rendering: optimizeQuality; although this should be the default. Perhaps you have another tag somewhere which is overriding the default?
From http://articles.tutorboy.com/css/resize-images-in-same-quality.html
If the intention is to get a better quality when the user prints the page you could use separate style sheets for print and screen.
<style>
#media screen
{
#origImage { display:none; }
}
#media print
{
#screenImage { display:none; }
}
</style>
...
<img id="origImage" src="original.jpg" />
<img id="screenImage" src="resized.jpg" />
I have a simple UiBinder widget containing a TextArea:
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<g:TextArea visibleLines="3" />
</ui:UiBinder>
I want to control the background color of this textarea for writeable and read only states. GWT uses the "-readonly" style name decorator to achieve this. So I try this:
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<ui:style>
.textBoxStyle {
background-color:yellow;
}
.textBoxStyle-readonly {
background-color:lightgray;
}
</ui:style>
<g:TextArea styleName="{style.textBoxStyle}" visibleLines="3" />
</ui:UiBinder>
Obviously this won't work because style names are obfuscated for CssResources resulting in something like this:
.G1x26wpeN {
background-color:yellow
}
.G1x26wpeO {
background-color: lightgray;
}
The result HTML for writeable textarea looks like this:
<textarea tabindex="0" class="G1x26wpeN" rows="3"/>
The read only textarea looks like this:
<textarea tabindex="0" class="G1x26wpeN G1x26wpeN-readonly" readonly="" rows="3"/>
How do I declare the style so GWT will obfuscate the primary part but not the "-readonly" decdorator?
I know that I can disable the obfuscation for the entire style name. But I'd like to keep the obfuscation while making use of the decorators.
At this moment (GWT 2.4) it is not supported, and it's not clear if/when it will be supported, see issue 4746 in the GWT issue tracker.
The workaround is to add #external, which disables obfuscation for those styles. In this case that would be:
#external textBoxStyle, textBoxStyle-readonly;
If you want to use this style for all your read-only TextAreas then I'd suggest just modifying the .gwt-TextArea-readonly style in your GWT theme CSS file.
Otherwise, I can only think of adding your custom style programmatically when you set the TextArea read-only.
PS: from the docs:
<set-configuration-property name="CssResource.obfuscationPrefix" value="empty" />` can be used for minimal-length selector names, but this is only recommended when the GWT module has total control over the page.
I recommend using this (with "empty" or "X" or other unused prefix) for much shorter class names - because at default settings you don't gain that much through obfuscation (textBoxStyle - 12chars, G1x26wpeN - 9chars, X0 - 2 chars ;)).
Why don't you try sth like this
public class MyFoo extends Widget {
interface MyStyle extends CssResource {
String normal();
String readonly();
}
#UiField MyStyle style;
/* ... */
void setEnabled(boolean enabled) {
getElement().addStyle(enabled ? style.normal() : style.readonly());
getElement().removeStyle(enabled ? style.readonly() : style.normal());
}
}
this would allow you change style if a text box is "normal" or readonly...
And off course, in the UiBinder you should have sth like
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'>
<ui:style type='com.my.app.MyFoo.MyStyle'>
.redBox { background-color:pink; border: 1px solid red; }
.normal { color:black; }
.readonly { color:gray; }
</ui:style>
<div class='{style.redBox} {style.normal}'>I'm a red box widget.</div>
</ui:UiBinder>
Try Now This One I Hope You will get it.
With the <ui:style> element, you can define the CSS for your UI right where you need it
Note: <ui:style> elements must be direct children of the root element
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<g:TextArea visibleLines="3" />
</ui:UiBinder>
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<ui:style field='MyStyle'>
.textBoxStyle {
background-color:yellow;
}
.textBoxStyle-readonly {
background-color:lightgray;
}
</ui:style>
<g:TextArea name="myText" styleName="{MyStyle.textBoxStyle}" visibleLines="3" />
</ui:UiBinder>
Isn't there a typo in your UIBinder?
You have:
<g:TextArea styleName="{style.textBoxStyle}" visibleLines="3" />
.. but I think you need to be using "stylePrimaryName", ie.
<g:TextArea stylePrimaryName="{style.textBoxStyle}" visibleLines="3" />
But I guess this question has been answered really already..
Here's something valuable I figured out by putting together info from other posts in this thread especially...
If you use #external, you can override gwt styles. The problem is that is this change gets applied globally! It is possible, however, to extend & override select attributes without effecting every instance of a widget type. (This like the programmatic styling method of creating a css class with a gwt class name + a suffix and using addStyleDependantName().)
Here is an example of using UIBinder + a CssResource to extend a gwt style. I left out the CssResource part, but you'll get the idea...
In your xxxx.ui.xml file, expose the gwt style, but don't mess with it!
<ui:style>
#external .gwt-Button; .gwt-Button {}
</ui:style>
Then, style a widget it by specifying 2 (or more) styles in the styleName attribute. I.e. the gwt style, and the one (or more) from your resource.
<g:Button ui:field="submitButton_" text="Submit" styleName="{style.gwt-Button} {res.loginStyles.submitButtonStyle}" />
Here's the css class:
.submitButtonStyle{
margin: 3px 5px 5px 0px;
}
In this case, I defined a button that is styled in the standard method (easily changed via module inheritance) but with a specific margin that will remain fixed. This didn't mess up the global style, it didn't require defining all the attributes manually, and allowed for swapping the global styling at will with clean.css, dark.css, etc.
