I have limited knowledge of CSS and JavaScript, but I am looking for a way to create a notification highlight that functions similarly to when someone comments on a Facebook post. When clicked, it should direct me to the specific comment with a temporary highlight.
Any help is greatly appreciated!
If you want to add some flair to your website, consider using the CSS3 animation property. Remember to include the -webkit- vendor prefix so that it is supported across different browsers. Information about other necessary vendor prefixes for CSS3 properties can be found on caniuse.com.
To achieve this effect, simply assign a special class to the element you wish to emphasize and implement the animation through CSS.
Give it a try:
.post{
padding: 1em;
margin: .2em;
background: #ffffff;
border: 1px solid #eceded;
}
.post.highlighted {
-webkit-animation: highlight 6s ease;
animation: highlight 6s ease;
}
@-webkit-keyframes highlight {
from { background: #ddddff }
to { background: #ffffff }
}
@keyframes highlight {
from { background: #ddddff }
to { background: #ffffff }
}<p class="post">This is just a regular post</p>
<p class="post highlighted">But this one stands out!</p>It appears that there are some challenges you need to address. Allow me to guide you through the reasoning behind each issue. Certain problems already have solutions available online, and I have included links to the relevant pages.
1) Handling a click on an element
2) Scrolling to a specific section of the page
Smooth scroll to specific div on click
3) Emphasizing an element
This task involves altering the attributes of an HTML element, such as its background color. It can be accomplished by modifying the class using JavaScript and utilizing CSS to style the element differently when it possesses the correct class.
CSS:
.element {
background-color: #0000ff; /* Default blue background */
}
.element.highlighted {
background-color: #ff0000; /* Red background when highlighted */
}
JS:
document.getElementsByClassname('element')[0].setAttribute('class', 'element highlighted');
You simply need to execute this line of JavaScript at the appropriate moment (after the scrolling has ceased - refer to step 2 for insights on how to do this).
4) Removing the highlight after a delay
Utilize JavaScript's setTimeout function to eliminate the highlight class following a delay:
JS:
setTimeout(function() {
document.getElementsByClassname('element')[0].setAttribute('class', 'element'); // Replace "element highlighted" with just "element"
}, 1000); // 1000 signifies a one-second delay
