I have checked many books and sites, where I can see that everyone is saying that it is a default property and we can not use top, right, bottom and left property, I can understand that. But if it is already predefined then why do we use it's syntax? Can anyone please tell me its use.
{position: static;}
We use it's syntax simply because we can make an element on a webpage change positions multiple times. Whether it's for animation purposes or for a real application it's always nice to be able to bring it back to it's default behavior (for whatever reason necessary).
For example, if you wanted a responsive website with an image in a special area, you could set that image position: relative for wide screens. Then when the screen size is reduced you can set it back to position: static , which (in my opinion) is easier to handle when the screen size is small (mobile phones).

I've noticed that when I add an HTML app in Rally/Agile Central, the height doesn't fit/adjust within the browser windows. This means that a vertical scrollbar is always added.
I'm using Chrome and Firebox, but they both have this problem.
Is there a way to limit the height of the custom app?E.g., to (height - 25) so that the browser scroll bar is not necessary?
Can you share some of your code? It might help in diagnosing what's going on. A couple ideas though...
Are you using a layout for your app? This often can help with scrollbar issues.
This guide may be helpful for learning to work with layouts: https://docs.ca.com/ca-agile-central/saas/apps/2.1/doc/#!/guide/layouts
If you're just using auto layout (the default, if you didn't explicitly specify one) then you can also try adding autoScroll: false to your app's config. Note this may cause your content to be clipped if you do actually need a scrollbar though.
Here is an examle with the std list app - and it's the same whether there is anything to show or not.
I'm thinking that it is the HTML app that doesn't take into account that there is a page title, in this case "*test layout scroll bars" - and somehow uses the "full height" = the entire frame (I'm not an html/css expert)
below i attached an app help guide screen. I am understanding how to build this screen.
If any body have idea please share here
View with semi transparent background color (backgroundColor:"rgba(0,0,0,0.5)";) and some images on top of it.
So, using images is bad. You'll need images for translations and if you do this as one image you'll need to ensure all devices are covered so your arrows point to the right element.
Minimise images == smaller app.
First thing you'll need to do is a create a blocker view -- so that's a view that will fill the screen and have a black background with opacity.
You can't apply that to the window as everything in it will be semi-transparent so:
Create a transparent Window that fills the screen.
Add to that window a view that fills the window and has opacity say 0.5 and black background
Add to the Window (not the view you just created) the other elements and button -- ideally, these should be individual graphics of the arrows, sized in such a way that you can position them based on the host element (the item they are pointing to / referring to). Use real text so you can handle translations / reduce file size.
So you'll need a way to associate each tip with a control they are anchored too, and that will ensure that regardless of the screen size, the tip will appear in the correct place.
First of all, always give a try before putting questions anywhere because it makes you learn things on your own for long time.
The easiest step for you to do this is to ask your designer to create a complete image just like that & you just have to show it on top.
If you have to show that image in different translations, then you can ask your designer to provide you required translations images.
My VB.Net application is using anchoring to force certain controls to resize to their container, eg a list box on a form. This is all pretty standard and easy to do. However having just released the application into production I've found that on one user's computer the anchoring seems to just be ignored. She has Windows 7, as do I.
So far example what should look like this:
instead looks like this
I asked her to try a higher resolution on her screen but that didn't to help.
On one of them I was able to fix it by manually setting the width and height in form load properties of the control instead of anchoring it, but it seems a bit backward.
It looks to me like the form has been resized to be too small for the anchoring to work correctly. Set the .MinimumSize property of the form to ensure the form does not get too small for your layout.
Older staff sometimes reduce the screen dpi to make text easier to read, which means the screen may not be big enough to display the form. To fix this, set the screen dpi back to something reasonable and increase the text size for readability.
Turned out to be that the display issues were caused by user having the "Font Size" setting on her computer set to 200%. To be honest I didn't even know you could do that.
This may sound strange, but I don't understand how designers determine the image widths in their bootstrap layouts.
Consider the following template:
http://startbootstrap.com/templates/blog-post/
The 900x300 placeholder image is clearly not 900 wide on desktop 1080p monitor. It only ever gets shown full size when the browser is around 1000px wide.
Q) Am I being dense here? How are these widths determined/decided upon?
This is important as I want to make some designs using bootstrap, but obviously I want to make sure I select appropriate image widths.
Many ways to do this, but simplest is to use Chrome's "Inspect Element".
1) Right-click on photo and choose "inspect element". Scroll down until you see diagram of it's dimensions, padding etc
2) Adjust browser width to max out photo width (in your example it's between 990px and 1200px)
2) Keep editing the the placehold.it image-width until the inspector diagram stops changing photo width (see attached photo). This tells you the max threshold, in this case is 940px.
FYI, you can also try to determine knowing your column widths, padding, margins, and assuming you have properly reset nested column padding, but there is a lot of assumption and calculation there, so I tend to use the inspector method, at least to confirm.
The WP responsive theme I'm working on:
http://www.wpexplorer.me/tetris/
I use Firebug for Firefox browser addon thingy to make changes before messing with the actual files. So if you have it or something similar, you will see that by adding position:fixed; to the #header section the header width shrinks well more than half its original size and the navigation menu is jacked up within the new shrunken space.
I have added other snippets of coding to the #header section like width:100%;, width:959px; and other percentages and pixels, which messes up the layout; especially when you resize the window down to what you would consider to be for a tablet and a mobile device - it's all out of whack. I can't get the sticky header for this theme to function or do right. Oh, I've also added z-index:200; to the #header section and margin:160px 0; to #main-content; these don't give me issues.
Adding the width: ; code to the #main-content doesn't seem to help either (which I read somewhere online that this was where the width code goes).
Anyway, does anyone know what code I need to make the header of this theme scroll up until it gets to the top of the page where it becomes sticky/static/fixed/on top (whatever the real term for it is) at all times? And, can you get it to work with the layout being in tact when the window is resized all the way down to the size of a mobile device?
Thanks.
This should work
#header-wrap{position:fixed;top:0;z-index:999;}
#pre-header{margin:20px 0 15px;width:960px;}
#main-content{margin:215px 0 30px;}
The position is fixed at the top using 0 with a z-index:999 you then need to set the width of the inner container pre-header 960px to match the rest.
You will need to setup the media queries for the other sizes you have setup. Easy, and Enjoy.
If you want the menu itself and not the social icons to become the top fixed bar without the social icons then you want to make a jquery scroll CSS change so that the #header becomes the fixed position.
It working with fixed header and social:
An illustration of it working without the social bar using a Jquery Scroll CSS change:
This is the way I would do it, I would move the menu down, and add the social icons to the menu itself. (Below is a screenshot of what I mean, the social icons are reduced to 75%)
PS. The social icons stand out to much so I would add a CSS3 Greyscale, and when the visitor hovers over them it turns on the color with a transition effect.
Hope this helps ;)
