Why does Dreamweaver add an icon to my "a" element? - html

I just found that, in Adobe Dreamweaver CS3, this code segment seems fine in the design view,
Test Anchor
but if I add an "id" attribute to this "a" tag, like this,
<a id="test" href="#">Test Anchor</a>
there would be an icon at the left side of the "a" element, something just like an open book. (I have no privileges to upload image)
What is the meaning of the icon? Is there anything that Dreamweaver implies? I've tried to google some groups of keywords, and got nothing but ads.
Any help? Thanks a lot!

This icon (should look like a shield with an anchor on it) is a Dreamweaver design view indicator. This indicator is used to identify "named" anchors. No image that will be uploaded to your site, so don't worry about that. Anchor () tags with an ID are considered "named" as you can add a hash to the end of your URL to have the browser "jump" to the named/ided element. If you file is test.html and you visit your page with test.html#test then the browser will load up your page and "jump" to the named anchor. In recent browsers (not sure how far back, but likely far enough to not worry too much about it now) anchors with an id attribute value will work in the same manner as those with a name attribute value.
If you do not like this icon appearing when you have a couple of options:
Edit (Dreamweaver on Mac) -> Preferences, Invisible Elements, uncheck Named anchors.
Or View -> Visual Aids -> Invisible Elements. This option turns off all invisible element indicators listed in the preferences, so make sure you know what things your turning off.

It's probably just using the symbol to identify text on the page that's a link, save the file and load it up in your web browser, chances are the icon isn't actually part of your code.

How to always add style in one site

I use a site at work that has unordered list "ul" with a lot of "li" elements without borders, I would like to always highlight the "li" elements to have better readability.
What I do at this moment is right click the page and open the inspector and add this line:
<style>li:hover {background-color: #ffff99;}</style>
It works but I'm wonder if I can do a plugin for this or if there is another way to do it automatically (I have already send a request to the developer of the site to request this change but while I wait I would like to know what would be the best approach to automate this task)
The list look like this:
File.txt 85215165
File2.txt 96312121
File3.txt 41212123
File4.txt 65623443
File5.txt 69532055
... and so on
(It's not a continuous string, the file name and the number are elements inside the one "li" element and I'm not able to select them at the same time with the mouse)
And it has no style so it's difficult (at least for me) to see which number in the right match the file name in the left.
Note: The list is generated with a script and when I try to see the code of the page (right click see source code) I don't see it, I just see the script, that's why I do it with the inspector
This may solve the issue:
Stylish or Stylebot -- Chrome plugins -- both seem to add your preferred CSS on top of the specific websites you choose.
Paste this in the browser console, slightly faster and easier than editing HTML tags from within the tree in the inspect element tab.
document.head.insertAdjacentHTML("beforeend", `<style>li:hover {background-color: #ffff99;}</style>`)

Markdown Anchor links can't be clicked twice

I'm writing some documentation using GitHub's built in wiki (using Markdown syntax).
The problem I have had with anchor tags is that once I have clicked that anchor once, manually scrolled down to it again, and try to click it, it won't work anymore.
a) The place where the anchor links jump to.
##<a name="listofactions">List of Actions</a>
b) An example of an anchor link
[Back to List of Actions](#listofactions)
I also tried html in markdown syntax
Back to List of Actions
And even tried linking to the full url with the # and anchor appended.
Back to List of Actions
They all work, but when I manually scroll down to the anchor link again and click it, it doesn't bring me back to (a) anymore. Unless I click on a different anchor link.
How can I write it such that the anchor links can work regardless?
There is nothing wrong with your Markdown. This is simply how browsers work. The first time you clink the link (when viewing the same page), the URL in the address bar of your browser changes from http://example.com/path/to/your/page to http://example.com/path/to/your/page#someanchor. As that is a different URL, the browser will navigate to the new URL by scrolling to the appropriate position on the page. However, as you read the page and scroll to a different position, the URL remains the same. Finally, the second time you click the link,the URL is already http://example.com/path/to/your/page#someanchor so there is no change in the URL and as far as the browser is concerned, you are already there so no navigation happens and the page does not scroll.
There may be some JavaScript tricks you can use to trick the browser into behaving as you want, but those won't work on GitHub as they won't let you include any JavaScript in your pages for security reasons.
What you could do as a workaround (assuming you have a long page and want to easily find the specific location again) is first click the [back] button (taking you back to http://example.com/path/to/your/page) in your browser's navigation bar and then click the [forward] button (returning you to http://example.com/path/to/your/page#someanchor) which should trigger the browser to navigate to the location and scroll the page.
Try this:
...
<a name="listofactions"></a>
## List of actions
Mind the blank line between the HTML tag and the markdown markup.
Then call it via [link-to-anchor](#listofactions)
Should work.
Hope to have helped!
Add the attribute target="_self"

HTML iframe with page links

I know using iframes is not always the best idea, but for my case it makes things easier. I have a website A which contains links to other parts on the same site (using <a name=...). I have a seconds site B which has an iframe containing A. Everything works fine, except the page hyperlinks, if you click on them, nothing happens.
Does anyone know if named hyperlinks are even possible in iframe? And if yes how to make them work.
EDIT:
Seems like I wasn't clear enough. The file is named test.html (http://www.domain.com/embedded/test.html) and contains a hyperlink at the top
Examples
then somewhere at the end there is a link
<a name="examples"></a>
So when you click on the top link the page should scroll down to the bottom link. I have a second page (http://www.domain.com/index.html) with the iframe containing test.html. When hovering over the link (inside the iframe), it shows http://www.domain.com/embedded/test.html#examples. I'm not and iframe expert, but this link seems as it would rather redirect to the actual file (to #examples), rather than jumping inside the iframe. As I said before when clicking on the link nothing happens. Just tested in in Chrome and it works. Seems like this is a problem specific to Firefox.
These parts of your question make me smell something: "links to other parts on the same site (using <a name=...)" and "named hyperlinks"...
A hyperlink for moving to an other part of the same page:
Goto BOOKMARK
And an anchor (bookmark) somewhere else in the same page:
<a name="BOOKMARK"></a>
These are working in every HTML-document, regardless they were shown in the iframeor not.
I had a similar problem. I too wanted a link in an embedded page to point to a bookmark in the containing page. But I am not sure if our circumstances are exactly the same.
A local link such as
<a href="#BOOKMARK">
will only look for an anchor in the same page as the link, i.e. in the embedded page. An approach such as
<a href="containing-page.html#BOOKMARK" target="top">
will only work if your link always references the same containing page. (The target needs to be specified, to display the page outside the iframe.) I am not sure if this will meet your needs.
If you want to re-use a common bookmark name in different containing pages, as I do, the design effectively requires the destination url to be treated as a variable, and that cannot be done using pure HTML. It requires javascript or similar.
It was in fact more elegant for me to add the bookmark link to the containing page, so that I do not need to standardize my bookmark names. This does not even need javascript, just a bit of css.
What I did was to position the bookmark link over the embedded display, so that it looks like it is part of the embedded page. In this example, the iframe is fixed at the top of the page and the bookmark link positioned over its top left corner.
<iframe style="position:fixed; left:0pt; top:0pt;" src="embedded-page.html"></iframe>
<div style="position:fixed; left:0pt; top:0pt;">
My Bookmark
</div>
With a bit of css refinement, this gives some flexibility of layout. For your issue, you may need to stick with javascript.

Can I turn off a link in CSS, e.g. for a bookmarklet install page?

I know how to use CSS to turn off or change the appearance of links on a web page (i.e. the anchor tags) but I'd like to turn them off completely. I'd like to do this for a bookmarklet install page. For example the Delicious tools page has a bookmarklet you can drag onto your browser's favourites bar. But on the install page because the bookmarklet is inevitably a link you can also accidentally click on it if you meant to drag it. This could confuse novices so I'd like to turn off the link behaviour in CSS whilst leaving the HTML intact as it is needed for the bookmarklet to work.
I doubt this is possible as it is a behavioural change not a formatting change, but it would be great if it is possible?
This is not possible with plain CSS.
However, you could prevent the browser from following the link by using javascript/jquery:
$("a.bookmarklet").click(function(e){
e.preventDefault();
});

How to scroll programmatically to a position in a page to display desired content (as opposed to display the top of the page)

I see on some website (like StackOverflow, yahoo, the US Homeland Security department, ...) a word associated to a link that, when clicked, not only loads a page, but also, displays that page at the exact location where the contain related to the word starts.
How can I obtain that with ASP.NET MVC? (by the way, do I need javascript for that?)
Thanks for helping
Go to the other content
<a name="jumpHere">Some content</a>
Also the URL can have /yourpage.html#jumpHere or with variables, /yourpage.html?var1=foo&var2=bar#jumpHere.
Since we're talking about the hash (#), it's usually used for jumping to a specific part of the page. Because of that, it won't reload the whole page. This is useful for web applications that move from one view to another using only AJAX. To make each view bookmarkable, JavaScript "saves" the state (what view you are on) using location.hash to the URL. The next time you open the URL, JavaScript reads it and loads the correct view. In HTML5 this is superseded by pushState.
1) Find the coordinates of the element on the page
2) window.scrollTo(x,y)
Its called an anchor tag.
Place this in your HTML.
<a name="name"></a>
If you call this URL, it will jump to that place.
html-file.html#name
See: http://www.w3schools.com/tags/tag_a.asp
You can use a named anchor to do this with HTML, without javascript. here is a link explaining this.
It is very simply done with id tag of differnt html elements
for eg :- an div element if it is having "footer" as its id and is placed at the bottom of the page then, http://url-address-to-thatpage.html#footer will load the page and scroll it too the footer. (adding the "#idoftheelement" after the page url)
It is also possible to load and scroll the page with javascript.
You need to create a named anchor within the page. This will have the result you're talking about, almost like creating a "bookmark" within a page. No javascript required.
First, create the anchor using the <a> tag with the name attribute specified (in this case, section1):
<a name="section1"></a>
Then, to link to that anchor from the same page, just use something like this:
Go to Section 1
If you're linking to that anchor from another page (in this case, mypage.html), append #section1 at the end of the url:
Go to Section 1 in MyPage.html
For more information, see here.
Another way to do it is with the "id" attribute if it's not an anchor tag you'd like to bookmark. For example:
<div id="bookmark1">Content...</div>
Then, you can link to it with an anchor tag like this:
Go to content
Or link to that spot on the page by appending a #bookmark1 to
http://yourwebsite.com/page#bookmark1
