Text disappears from navbar after selecting anchor link

Recently, I've been experimenting with Twitter Bootstrap and have found it to be quite delightful.

I managed to create a fixed navbar that sits at the top of my website. Inside this navbar, you'll find my logo, a header, a few links, and a dropdown labeled "Jump to:". Clicking on this dropdown reveals a menu with four links that will take you to different sections within the page. All links are functioning perfectly.

My current struggle is that the fixed navbar is obstructing the headers of each section since they now appear at the top of the page. Is there a way for me to prevent this from happening? Perhaps some jQuery magic or another solution?

Answer №1

It seems that you are inquiring about an anchor jump feature, which positions the corresponding anchor at the top of the viewport and below the fixed navigation. I encountered a similar issue and implemented the following code:

/* Code for fixing anchor jumps */

var nav_height = 77; // pixels

$(window).bind('hashchange', function(e){
    if($(location.hash).hasClass('anchor')){
        scrollBy(0, nav_height);
    }
    return false;
});
$(document).ready(function(){
    if($(location.hash).hasClass('anchor')){
        $('html,body').animate({
            scrollTop: $(location.hash).offset().top - nav_height - 10
        }, 10 );
    }
});

To enable jumping to specific elements, simply assign the anchor CSS class to those elements.

Answer №2

The CSS language also includes a scroll-margin-top attribute which defines the scroll margin of an element from the top side. To implement this, you must assign a class to the anchored element, such as .anchor Here is an example of how you can apply this:

.anchor {
    scroll-margin-top: 77px;
}

Answer №3

To ensure proper spacing, remember to adjust the following CSS:

body { padding-top: 70px; }

This tip is straight from the official Bootstrap documentation.

Adding padding to the body is crucial when using a fixed navbar to prevent it from covering your content. Feel free to experiment with different values or use the code snippet provided below. Remember, by default, the navbar has a height of 50px.

Answer №4

You can achieve the same result without using JavaScript:

a:not([href]):before {
    display: block;
    content: "";
    height: 80px;
    margin: -80px 0 0;
}

By utilizing a:not([href]), you can ensure that your links do not have a href attribute. Feel free to modify both instances of 80px to suit your design needs.

Answer №5

Indeed, utilizing 2ndkauboy's method yields positive results. To summarize:

  1. Remove the 'px' from the nav_height variable (just as suggested)

  2. Apply the anchor css class (per 2ndkauboy's guidance) to the <div> element instead of the <a> tag, like so:

    <a href="#jump_here">click here</a>
... additional code here ...
<div id="jump_here" class="anchor">
    ... content ...
</div>

This explanation proves valuable.
