I'm dynamically generating an imagemap for a chart tool I have.
I was hoping to be able to set a border or color on the area tags so I could check everything was being generated with the right coords, but a little research shows this is not possible.
So whats the easiest way to check my image map is correct? Are there any browser tools which will "visualise" the areas?
What about using JavaScript (and jQuery) to test it?

This plugin will highlight image map areas.
You can use FireBug for that:
Right-click your image and choose "Inspect Element with FireBug"
In the HTML tab of Firebug, the image tag is highlighted: locate and expand the associated map tag, which usually is right after it
You can now place your mouse over each area tags to see them highlighted over your image
One way to visualize an area tag in Chrome is to add a tabindex to the area tag(s) you want to see, and then click or tab to it. Chrome will nicely highlight the actual outline of the clickable area.
This solution unfortunately doesn't work in Firefox.
Image Map Editor is a plug-in for Firefox. It is the best tool I have found so far, makes creating, inspecting, and editing image maps very easy.
In Chrome you can select the area of the image map and click on the three little dots
to the left and then select "focus"
Never thought I would ever say that, but this is one of the few cases where Dreamweaver could be helpful. You'll have an interface, you will be able to work with anchor points and set your imagemap easily.

I had a quick search for this problem and couldn't find anything that satisfied both parts so I hope this is ok to ask:
I am creating an interactive map which has an aerial image of a location as a background, with small icons overlayed over the top. These icons, when clicked should open a popup window with images or videos that have been taken in those locations, much like a google map.
I have found code to allow me to layer images over each other here:
Html Image over image
And I have found code for a popup here:
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_popup
And I can get both of these elements to work separately on my webpage, however I'm stuck as to how to combine them so that the image I have overlayed can be clicked on to trigger a popup.
It's been a while since I have coded in HTML and I can usually handle these kind of challenges but I'm finding myself a bit out of my element here.
Thanks!
I am very interested in improving my browsing experience by never seeing images of the cast of "Friends" again. I know that I can uncheck "show pictures" in IE's advanced options, but I would prefer to just filter out certain images based on the description text. Is it possible in any browser to show most images, but hide an image if the description contains "Aniston" for example?
Well, you don't know the "description"/tag of the image of a website before you are on it and inspecting it. So to my knowledge it's not possible yet.
You could write an Extension to do this, or add a bookmark with an Url of:
javascript:(document.querySelectorAll("img[alt=Aniston]").forEach(img=>img.style.display="none"))
to your Bookmarks. Everytime you click on that bookmark, all image elements with an Describtion of "Aniston" will be hidden.
If you want an Extension to do this, contact me.
There's an element that appears on the site, but I can't seem to find it in the inspector of the browser. I would like to hide it somehow.

It is the "BEZÁR" word with white color, next to the "Becsuk" button, when clicking on the "MÉG TÖBB" button (to expand the content).
This problem shows up when I turn on the "Automatically add paragraphs" in the WordPress SiteOirgin editor; but I need to use it, otherwise the content falls apart.
EDIT: This is with the plug-in called: "Collapse-O-Matic"
You will never find it since it's not an element.
It's part of the image in the background http://gdhbau.hu/wp-content/uploads/2018/03/bemu-bg-large.jpg
I see this type of menu all over the Internet as a way to filter out data:
Does it have a specific name? I'm particularly interested in seeing how the pushed in effect is achieved. I've gone through the Chrome developer tools but viewing the CSS applied Chrome only returns a few classes and not the id of the element.
The menu type does not have a specific name as far as I know (although for all effects and purposes it is a set of radio buttons).
The pushed in effect is caused by an inset shadow and darker background color.
Here is a JSFiddle.
That menu is from Google maps.
It is what I might call an "icon" menu.
Buttons are not pushed in.
Instead, the images are swapped in and out depending on what is chosen.
Javascript is used to change the images and the content below the images.
Use Chrome and go to Google Maps. Type in an address and then click Get Directions. Once the buttons appear, right click on one of the button and choose Inspect element. That will show you the code that Googe is using.
The pushed effect is simply an image applied to the element when it's clicked
They're usually done with sprites
Here are some sprites from google
When the image is hovered/clicked a different spot on the image is used as the background for that element.
I have a very peculiar requirement and I am not an HTML expert. I need to create a CHM (Compiled HTML File) in which I want to use an image (a single screenshot) that will have parts of the image linked to other sections in the help file. In other words I want to hover the mouse to individual regions in the single screenshot to link to other parts of the help file.
Just for information the screenshot is a shot of various buttons and checkboxes that are a part of the application.
I do not wish to break up the single image into multiple images and then link each image to another part of the help file (that explains the function of the image). I think that is very much possible and not a problem at all.
If you can just in brief explain how this can be done or provide me a link I would be grateful.
You can use an Image Map for this. You basically have a normal image and then place various invisible shapes over the image. You can then use all the shapes for hover and click events.
With some googling I found this: http://www.htmlcodetutorial.com/images/images_famsupp_220.html
Consider using an HTML image map, which you can create online here. An HTML image map is a set of tags describing various regions of an image that can have links of their own.
Aren't those called "image maps"? HTML has a tag called <area> (and <map> itself) which allows you to do this.

You'll need to use an image map for this. If you want to get a bit fancy and have rollover's for this you could think about using the ImageMapster jQuery plugin.
