I want to learn how can i design a site which background and images color will be changeable by the user. Colors could change by only one color within 4 colors such as green, blue, white etc. in the sites such as msn, yahoo etc. But, there was no effects like drop shadow or gradient overlay in that images. However, I want to change color of images which applied effects such as drop shadow, gradient overlay. Moreover, with each color. Just like chameleon.
I can put a text link on the right of the top. A color selector like at Photoshop can open, when the user clicked this link. Color selector generates a hex code according to selected color. Color of site changes to color which the user selected.
I changed an image background color which is transparent by using JavaScript DOM. Color of transparent area in the image will be the same with the background color of div tag which contains this image. But, if the image has got effects like shadow, overlay etc., the changing color will be disable.
How can I do it, and which technology will I use, jQuery, Ajax? How I create a site which color could change.How I create a site which color will be changeable by the user.
Just like chameleon...
Hmm, well this might take a while to implement, if you're starting with little knowledge.
My suggestion, to get you started, is to have a javascript which changes the class of the body element according to a selection the user makes. So let's say I visit the page, the <body> tag has no class, and default css is used.
Then I click on the link to make things red. Using javascript, or jquery, give the body the class "red-body".
Have css in your stylesheet which only works for elements which are children of an element with this class.
Html:
Go Red
jQuery
$('.go-red').click(function(){$('body').removeClass();$('body').addClass('red-body');});
So if you have code like:
#navigation li{color:#000;}
.red-body #navigation li{color: #af000;}
This will make this possible. This means you can do it all with just one stylesheet, which I think is the best way.
There are a number of ways to store the users choice. One of the easiest ways is to set a cookie in their browser. You can do this with javascript, here's the introduction from w3schools: http://www.w3schools.com/JS/js_cookies.asp

is there any alternative to the depricated"HorizontalDivider" in SAPUI5? Since Sap doesn´t mention any alternative, I ran over something like "" Element that draws a Horizontal line?
It is better that you use a toolbar element as it has the bottom border. When you use the html hr tag, it does not respect the theme color while the toolbar use the theme color and also its spacing policy.
<sap.m.Toolbar width="100%" height="1px"/>
It the following picture you can see what is the result of using a toolbar with 1px height.
And in the following picture the result of using html hr tag.
Or you can use any boxing elements of the UI5 and just play with its class. For example you can assign the class sapMTBStandard to your element to make a bottom border with suitable color in your theme.
<html:hr></html:hr>
Make sure you add xmlns:html="http://www.w3.org/1999/xhtml" library
I'm using Bootstrap glyphicons for a web app and love the flexibility of being able to leverage them as fonts, since that's what they are, not graphics. However, I'm running into a challenge with the glyphicon-remove-sign icon, which has a colored circle surrounding an otherwise empty "x". I like the default look of the black surrounding the "x" and want to use it to close a rounded-cornered iframe. But, because that "x" is empty, it displays whatever is behind it:
Ideally, I'd want to have that hollow "x" be a different color like white, easy enough to do with background colors, except that creates a box around the otherwise vectored font and looks unsightly for my usage, which has multiple colors to contend with behind the icon:
The question is: is there a way to just fill in the empty space inside the hollow area of this glyphicon without this kludgy-looking box? I looked at using a clip-path with the background color, but that won't work with IE. I welcome any recommendations anyone may have for a fix here -- thanks in advance.
create a wrapper div of the glyphicon, give it border-radius as to imitate the circle streching it and then give that background color
I'm trying to create a live tile for my application, using a user control.
The user control contains a grid, an image and a rectangle filled with color.
Now here comes the funny part.
I want the rectangle to act as a background for the tile's title, and the image to fill the rest of the tile. And i said to myself, well, lets put some rows in that grid and set the like you usually set them in a WPF/SL application.
I then write the entire thing in a WBM and save it to isostore.
The problem is, the parser seems to ignore the presence of grid's rows. regardless of what I try, the rectangle is not shown, and the image covers the full tile, when it should only cover the first row. It is as if the grid didn't even existed.
Another funny aspect is that it doesn't matter if I use rows or columns, the result is the same.
Any ideas?
Are you using the following method?
Dynamic LiveTile - adding background image?
I recently implemented a Live Tile using a Grid with Rows and Columns for layout of some TextBlocks. I encountered similar challenges, so I placed the control that I was using for my Live Tile on a blank page in my app to better see what was happening. Does the control render correctly when displayed on a page (versus being rendered to a WriteableBitmap)?
Another idea. Instead of trying to position the Rectangle relative to the tile's Title, why not leave the Title property blank and put the same text in a TextBlock within the user control?
If you are careful about the font and positioning of the TextBlock, the text on the resulting background image can appear indistinguishable from text displayed from the Title property. I decided to follow this strategy myself. I found the font information in the following answer:
Font size and family for a tile's title
Otherwise, could you post an example of the XAML you are using?
I successfully changed the background color of a Gtk.TextView (GTK3) with method override_background_color:
color.parse(self.settings.get_string("bgcolor"))
self.ui.NoteView.override_background_color(Gtk.StateType.NORMAL,color)
I also override the foreground color.
Unfortunatelly in that case making a selection in the text is invisible.
How can I modify the background and foreground color of a TextView without loosing the visible text selecting?
It's best to format the text in a GtkTextView by using GtkTextTags. You can apply any sort of text formatting(background & foreground colors, font, size, weight, etc..) to any portion of the text.
Click here for an example.
Hope that helps!
By the way, what you're doing is changing the style of your TextView. In Gtk it's best to stay away from doing this, especially if you aren't in a controlled environment or plan on releasing your software for others to use, because gtk's philosophy is to leave the styling and theming up to the end user for their own personal touches/needs.
This is why you are getting some unwanted results by overriding style colors.
In terms of a GtkTextView it does however offer simple formatting of the text(even support for adding images/widgets) via use of GtkTextTags as the link shows above.
I am trying to implement a control to edit text that will display the text in multiple colors. None of the solutions I have attempted yet have been good enough.
UITextView cannot accomplish this. All of the text must be the same color.
Using CoreGraphics to draw the text does not allow the text to be selected.
Using a UIWebView, DIV and PRE tags cannot be set to contentEditable on Mobile Safari.
Currently playing with using an off-screen TEXTAREA and an on-screen DIV to show the rendered text. This works pretty well, except supporting all of these at the same time seems impossible: click-to-type, click-to-move-cursor, click-and-hold-select/copy/paste.
Anyone have any tips on this predicament?
I've been trying to find any preexisting library out there that will accomplish this in a good way, to no luck. I'm open to any ideas!
Well, just pulling an idea out of my... let's say hat.
Could you put a transparent UITextfield over a view that draws the text? If the background was clear and the text color was clear the user could not perceive it but it should still respond to all commands. As the user enters and edits text you could draw the results on the view underneath.
I think the selection would work without any modification at all. When the user selected the clear text, it should create the illusion of selecting the drawn text automatically.
Like this one? StyledText http://three20.info/gfx/overview/styledtext.png It's in Three20 .
Here is an idea. I have no idea if it would work.
If you are only using colors, and not styles, the a UIWebView with colored text might layout text in exactly the same way as a UITextView. You could put a UITextView with invisible ink (text and background fully transparent) over a UIWebView and mirror the contents with colors in the html. I assume you can do scrolling with javascript along with the colored layout.
