Targeting a disappearing element for its CSS

    Have you ever tried to target dynamic elements such as as Tooltips under bootstrap only to find that they disappear when you try to inspect them? You’re not alone.

    Fortunately (and inspired by this post), there is a workaround in case you find yourself in a similar boat.

    The Problem

    You locate the popover element you’d like to change, right-click then select Inspect Element and then element itself disappears - along with any hope of you finding the related CSS.

    The Solution

    We need to use a bit of ingenuity here. This is where the browser (in the case of Webkit, such as Google Chrome etc) debug facilities come in handy.

    1. Fire up the page where the element appears that you want to inspect
    2. Press F8 to open the developer tools
    3. Click on the console tab
    4. Paste the below into the console
    setTimeout(function(){debugger;},5000);
    

    Note that 5000 is adjustable (and the inspiration for the Mission: impossible - Rogue Nation sequence 🙂 ) It should look like the below - essentially, 5000 is 5 seconds… Now you see (hopefully) the paradigm.

    1. Now press enter
    2. You have 5 seconds before the debugger will launch, which should be enough time for you to active the element you want to target

    1. Wait until the debugger fires

    1. Now select the element you want to inspect in the usual manner

    1. Expose the CSS as required

    Customise as necessary 🙂

    @Sala the only way you can achieve this is to use a robots.txt file and disallow access to those links.

    @DownPW Looking at the underlying code, class start is being added on hover by jQuery in this function document.querySelectorAll(".button-gradient, .button-transparent").forEach((button) => { const style = getComputedStyle(button); const lines = document.createElement("div"); lines.classList.add("lines"); const groupTop = document.createElement("div"); const groupBottom = document.createElement("div"); const svg = createSVG( button.offsetWidth, button.offsetHeight, parseInt(style.borderRadius, 10) ); groupTop.appendChild(svg); groupTop.appendChild(svg.cloneNode(true)); groupTop.appendChild(svg.cloneNode(true)); groupTop.appendChild(svg.cloneNode(true)); groupBottom.appendChild(svg.cloneNode(true)); groupBottom.appendChild(svg.cloneNode(true)); groupBottom.appendChild(svg.cloneNode(true)); groupBottom.appendChild(svg.cloneNode(true)); lines.appendChild(groupTop); lines.appendChild(groupBottom); button.appendChild(lines); button.addEventListener("pointerenter", () => { button.classList.add("start"); }); svg.addEventListener("animationend", () => { button.classList.remove("start"); }); }); }) The CSS for start is below .button-gradient.start .lines svg, .button-transparent.start .lines svg { animation: stroke 0.3s linear; } And this is the corresponding keyframe @keyframes stroke { 30%, 55% { opacity: 1; } 100% { stroke-dashoffset: 5; opacity: 0; } } It’s using both CSS and SVG, so might not be a simple affair to replicate without the SVG files.

    @phenomlab said in tag icon in front of tags: @crazycells Are you using Font Awesome Free ? If so, try this span.tag:before { content: "\f02b"; font-family: "Font Awesome 5 Free"; margin-right: 5px; margin-left: 5px; font-weight: 900; } yeap, this worked thanks a lot.

    @cagatay you’ll need to define this in the body tag (or another element if you want greater or more granular targets) - for example body { font-family: "Poppins"; font-size: 16px; } Essentially, you use the font-size CSS directive.

    @DownPW the ‘js’ code for the banner takes the time from the client, so what it displays really depends on the regional settings for the operating system. I’ve not seen this issue myself but would like to see some examples of screenshots if possible.

    @riekmedia I’ve applied some new CSS to your site. Can you reload the page and try again ? For the record, this is what I added #footer { background: #2d343e; border-top: 4px solid #2d343e; font-size: 0.9em; margin-top: 70px; padding: 80px 0 0; position: relative; clear: both; bottom: 0; left: 0; right: 0; z-index: 1000; margin-left: -15px; margin-right: -338px; } The /categories page seems a bit messed up, so looking at that currently EDIT - issued some override CSS in the CATEGORIES widget <!--- CSS fix for overspill on /categories page - DO NOT DELETE --> <style> #footer { margin-right: -45px; } </style> That should resolve the /categories issue.
