Chrome character that is invisible but searchable - html

I work in a research project, and we have a python script that generates html texts that have a number of words highlighted. I would like to make the position of these highlighted words in the texts visible on the scroll bar. One way we could do this is by adding a special character (e.g. "$") after each of the marked words, and then run a search on this character.
We would like this character to be invisible, in order not to mess up the text visually.
I tried making a span class named "hidden", with font size 0. This does the job of hiding the $ sign, but Chrome search suddenly does not indicate the location on the scroll bar anymore. The search box still shows there are 57 results for "$", but the scroll bar highlights are gone, and clicking the "up" and "down" buttons does not bring me to the location of the next result.
I also tried inserting invisible commas (ampersandic;) in the text, but did not manage to search for these.
Other solutions, anyone?
Thanks a lot!

You can use opacity: 0 which will visually hide the element but it will not remove the space of character.
To minimise the space you can decrease the font size to the minimum like font-size: 1px

How to style misspelled text like Weather.com (Dashed underline instead of squiggle)

Weather.com is the only example I know of that is doing this, showing a dashed red line under misspelled text instead of squiggles. This is on Chrome in Windows 7
What I'd like to replicate
Any ideas on how this is done? Unfortunately going to inspector clears text from the field.
What most sites show
This turns out to not be a style, but rather an effect of a precisely sized text box/precisely tuned line height. The squiggle is 2px tall, but the bottom 1px was cut off, giving it the appearance of a dashed line, but in fact it is not.
This method can be used to replicate the effect shown IF you are using a font where the letters that extend below the baseline don't go so far down that they touch the spellcheck squiggle.
It seems possible to move the squiggle independently of the text, which could possibly present a way to do emulate this style with any font.
If I find a way to do this, I will update further.
This is a browser feature that can be achieved (at least in Webkit/Blink) on input fields and contentEditable elements with spellcheck="true". Not every browser will implement it the same way. For that, you would have to build the text markers yourself in conjunction with a dictionary service (like Google Docs does, as one example).
https://jsfiddle.net/bn7pfyf3/
(change the "true"s to "false"s and you won't see any highlights on focus)
In Webkit/Blink, this is a DocumentMarker type (which is used for Ctrl+F, highlights, typos in input fields, and more). They are not exposed in the DOM or CSS.

Can't select text in contenteditable in Chrome by using keyboard

In Chrome, I can't select the contenteditable text context by using the keyboard in Chrome when the text contains a long string that wraps to the next line.
This repro's in Chrome (latest; Chrome 47 at the time of my writing this).
Repro steps
Click to place the cursor at the end of the contentedtable div (in the snippet below).
Hold shift and hit the up arrow a bunch of times.
Expected: All text becomes selected.
Observed: The text before the space ("foo") is never selected.
Here's the code. NOTE the character after "foo" is a space, not a newline!
<div contenteditable="true" style="background: #ddd; width: 200px; height: 100px;">foo asdfjkl;asdfjkl;asdfjkl;asdfjkl;asdfjkl;asdfjkl;asdfjkl;</div>
Actually, that's the correct behavior of textboxes in general.
In this case, you see the two words in different lines because the second one is wider than the container, so you see a line break and you try to use the up arrow to select "foo".
But, as you say in the question, after "foo" there is a space character, so you must use the left arrow to select it.
Just imagine the same case but with a full width textbox, you would only try to use the left arrow. Only the style changes here, not the behavior for that specific content.

Auto suggestion Dictionary for div contenteditable..(don't show popup box just suggestion beside word)

Is there any plugin available for autosuggestion for div contenteditable=true tag??
By typing a single letter it shows whole word as a suggestion..
I tried many plugins like auto.js n complete.ly but not working for div..

Reduce area of svg text

I am currently creating a word cloud using an in house developed library, it uses the svg element text to display the words, the problem I have encounter is that the area of some words sometimes overlaps other words as you can see if you inspect test1 in this jsfiddle, this becomes a problem if the words must be clickable.
I want to know if it is possible to reduce the area of the text to the minimum, just wrapping the word, a small padding is accepted.
I have already tried the solution posted in this answer but it didn't work.
I would prefer a css solution if it exists rather than messing with svg but if there is no other option that will do.
Edit: Ok, enough reputation to post images. What I currently have:
What I would like to have:
There are two problems; I currently have only a solution to one. Your text example is misleading. Try Text1g instead to see the descent (i.e. the amount of space below the baseline which the g needs). If you do this, then you'll see that the texts really overlap - you just don't notice because your test text doesn't contain a good set of test characters.
Apart from that, I see that the element is 67px high while the font-size is only 60px. I don't see where the additional 7 pixels are coming from. It's not padding and not margin :-/
Why do you need to know the minimum bounding box?
If it is because you are linking with the element, or applying click events to the words, then you should investigate the pointer-events attribute.
You possibly want something like:
<text ... pointer-events="fill">ejecutar</text>
You will only get events when the pointer is over the fill of the words. This might be a bit fiddly for clicking though because the holes in words will not be clickable.
You could ease that by putting an invisible <rect> of an appropriate size in front of the word with pointer-events="fill". The "fill" value will attract events for where the fill would be even if it is invisible. However that requires you know the bbox of the word, which we already established you don't have (?).
You could give the words an invisible fat stroke and use pointer-events="all". The invisible stroke will make the clickable area (invisbly) fatter and hence the inter-word holes smaller.

Getting text at clicked location in an HTML element

I have a div element containing some text. When the user clicks a word inside that div I'd like to highlight just that word.
In order to do this I need to know what character position in the text the click occurred at, so I can then locate nearby whitespace and insert some formatting around the word.
Finding out where the click occurred within the text is the trick here. Is that kind of thing possible?
If your page is auto-generated, you might consider pre-processing the page by putting a <span class = 'word'> around every word in every selectable div. You might be able to this with javascript after the fact, and I think that would be your solution regardless, but pre-processing would make it easier.
The problem with relying on the absolute position of the word is that users can scale their fonts, which makes this task especially hard. By wrapping a span around every individual word, you can easily select which word was clicked by applying the click event to the span elements.
