I've got a tough one. I work for a company that uses a sharepoint that is 100% text based due to varying network performace issues accross the world. It provides the option to input HTML for styling but scrubs any javascript. I do not have access to code CSS and I'm assuming jquery is not available.
I would like to embed images into the sharepoint as a proof of concept by taking advantage of a floating div (or iframe) that displays with an href to display a png file stored on a server. I don't want the div (or the image) to load unless the user clicks a link or a button.
I'm pretty amature at anything other than basic HTML formating. I'm not even sure it's possible to do something like this with only html.
Thank you in advance to anyone willing to take a stab at this.
You could do it with this HTML, which is ugly and unmaintainable.
Use an iframe with scrolling="none". Use width and height attributes to give it dimensions.
Inside the iframe have your img elements with an id attribute. Ensure they're spaced with enough vertical space so they can't be seen by default, and appear isolated when viewed later.
Link your links to those id attributes, e.g. link

I am looking for a way to remove DIV's from a website when it loads. The website is not local, it's a live site. It also recognises that Adblock is installed and prompts these DIV's until it is disabled.
I was looking at using the Adblock Plus filters but I don't know how I would accomplish the removal of the DIVs because their characteristics are not the same, each time the webpage loads. Here is some info on the site. I will also provide a screenshot of what exactly I would like to remove.
Name of website: http://www.tweaktown.com/
Element to remove: Multiple DIV Elements
The DIV's are generated with random Class' and ID's.
There are DIVs within other DIVs that need to be deleted.
Image showing DIVs/IDs and Validation
I'm hoping there Is some way to validate against the tags strings as shown in the Image
Why do images defined in CSS (like backgrounds, lists marker, ...etc.) not behave in the same way in the browser as HTML images? For example, they can't be selected by the mouse, and you can't right click on them.
Images are generally used in CSS for one thing, backgrounds. Which means they aren't used for the same things HTML images are being used for (displaying the actual image as part of the content).
When an image is part of the content, it can be saved and copied etc, because it
is likely to be considered interesting by the reader. Backgrounds (or list-markers etc) however, are less likely (unless the reader is a developer) to interest the reader enough to want to copy them. Instead, the focus is on the actual content of the element (which the background was applied to).
I guess it is a question for browser vendors why they allow certain behavior only when dealing with <img> tag.
However, you can use dev tools/Firebug/whatever and you can download the image file.
First time overflowing the stack.
I'm making a website with several html pages that are identical except for the fact that they contain different images that are more or less identical in size - and thats how they are named, by the jpg that they feature.
The pictures look great with the website, but I have a 300 pixel header that pushes them downward > forcing you to scroll down to see the full image. This is built into the shared CSS for all these gallery pages.
I have simple text links below the images that are hard coded to point to the next image in the gallery. (I have a list of the 20 images im displaying). When someone clicks the image, it goes to that page and resets the scroll to the top, which makes the header push the image area down.
Can anyone tell me how to prevent the scroll reset behavior of the new link?
Without using something like jQuery, you could link the pages such that you have an anchor tag like <a name="gallery"></a> above the images on each page and when giving the link to the various pages, append a #gallery to the url such as Next Image. This is duplicated on each page however, and will not produce a robust webpage. You'll want to change things in the future and this will cause problems and further work, so I would consider a dynamic alternative.
Note this won't look as seamless as with jQuery and using AJAX to load in the images when needed. Or better yet, as most JS galleries work, load the images into the page invisible at first and then with JS have them show up on the link click. The benefit of this would be that you could generate the links in JS using the provided images. If the images are large enough that they may cause considerable lag on page load, consider making placeholder images of some sort. In any case, take a look at lightbox 2.
Also, I didn't get the feeling you were using any server side scripting to create this gallery. If the js solution doesn't suit you or you find the added benefit of generating part of the website automatically based on the content need at the time, take a look at using something like PHP, Python, Ruby, etc. If it's just a simple website you're after, a great solution might be Wordpress.
You could have one page and just replace the images?

Now of course you change the function to work on a "previous/next" button system, assuming you have a photo gallery of some sort.
Please post more details.
You want your link to look something like this:
<a href="http://www.w3schools.com/html_links.htm#tips">
Visit the Useful Tips Section</a>
and you want to give your image an id="tips" in this case.
Check out this fiddle to see an example. The only difference is that your href will have the rest of the url in there like the code posted above.

Can you explain to me, at a very high level, what I would need to build an image carousel for the web, please. You can use data structures and general computer science terminology - but nothing language specific.
E.g:
Store all the images in an array or linked list
When the carousel is loaded, resize the displayed images as X% window size
When the next button is pressed, imageA moves to a hidden html element.
Et cetera.
I hope that makes sense.
Thanks.
You don't want anything language specific but you want to know about carousels on the web and you've tagged this with 'html' and 'css' so I'm going to assume that I can talk about HTML and CSS but I'll try to keep it high level.
If we ignore Flash, then you're left with HTML + CSS + Javascript. The common way to do this is to arrange the images or their thumbnails (don't resize via HTML - its doesn't look good and can increase your page load time) in HTML elements that are themselves contained in one or more layers of wrapping elements. So the whole set of images strung together might be wider than the viewing window. CSS is used to manage their exact layout and to keep them from overflowing the viewing window. When I say window, I just mean the portion of the page in which you want the carousel to appear. Then Javascript is used to change the CSS properties of one of the HTML elements that is wrapping the images, causing it to scroll or shift position.
With HTML5, you have more options, but the above is the way things have usually been done until now.
Finally, if you are going to actually implement this, there are a number of scripts available that will probably meet your needs, but if not I highly recommend using a Javascript framework like JQuery - it will make things much, much easier.
If you want to build it by yourself, one straightforward way would be to have a master div and all the images in it, lined up horizontally. Have the overflow set to hidden on the master div. Then use javascript and set scrollLeft as the user clicks the next, previous buttons.
Is it possible to use CSS to work like frames?
What I mean is, when we use frames (left, right for example), clicking on left will refresh only the right section using the 'target' attribute.
Is it possible to create this effect with CSS?
Thanks.
Using frames is usually a bad idea
To answer your question, no, CSS cannot be used to work like frames. CSS is used to changing the style of HTML and as such, cannot actually change the content of a page. It can be used to hide content, but I don't think that is what you require.
However, I feel in this case you may be asking the wrong question. As frames are usually the wrong approach.
When starting out in web design, frames seem like a great idea. You can seperate your navigation from your content, your site will load quicker because the navigation is not loaded every time and the menu is always visible, even when the page is loading.
But, actually, frames are incredibly bad for your usability.
Your users cannot bookmark individual pages
Printing is broken
Standard features in a browser like open in new tab often breaks
Users cannot copy/paste the web address for a specific page for sending to a friend
Frames do have their uses (e.g. Google image search), but for standard navigation menus they are not recommended. Try creating a page in a dynamic server language such as PHP or ASP.NET.
These languages have ways of creating standard elements such as your navigation menu without the use of frames.
No, this has nothing to do with CSS. CSS is for styling elements only. What you are looking for is an IFRAME. And IFRAME can be given a name
<iframe name="my_iframe" src="xyz.htm"></ifram>
and then be targeted in a link.
I've got a design that relies on framed content using CSS. You can do this by using overflow:auto, however it won't do what you want, i.e. loading certain portions of a page. To do this you'd need to use some AJAX library such as jQuery to load the content area dynamically. This is quite dangerous though as your URL may not relate to the current content of the page.
You could probably do something with the overflow part of CSS.
If you set up a div with overflow:auto with a fixed width and height with alot of content you will get scrollbars. Potentially you could use anchors to get content to move to be viewed within the div.
This means that all your content is in one page and it is just moved around with the anchors. You could do a similar thing using a jquery tabs plugin too.
I have never tried this and it might need javascript to get it to work fully.
