Preventing CSS elements from shifting during transitions

Whenever I apply a Transition to a CSS element, the content below it shifts. Here's an example on JSFiddle: http://jsfiddle.net/pgdxd7su/ (Please refer to the JSFiddle link as the code snippet may not work correctly).

h1{
font-size
}
h1:hover{
         display: inline;
         font-size: 3em;
         -webkit-transition: font-size .2s linear;
         -moz-transition:    font-size .2s linear;
         -ms-transition:     font-size .2s linear;
         -o-transition:      font-size .2s linear;
         transition:         font-size .2s linear;
        }

<!DOCTYPE html>
      <body>
        <h1>Hello</h1>
        <hr>
      </body>

Is there a way to address this issue and prevent the

from moving?

Answer №1

To ensure consistency across different browsers, a simple solution is to modify your HTML code as follows:

 <div id="h1box">
         <h1>Hello</h1>
    </div>

Once you have updated the HTML markup, you can apply CSS styles like this:

#h1box {
    position:relative;
    height:80px;
    border-bottom:1px solid #333;
}
h1 {
    position:absolute;
    top:5px left:5px;
}
h1:hover {
    display: inline;
    font-size: 3em;
    -webkit-transition: font-size .2s linear;
    -moz-transition: font-size .2s linear;
    -ms-transition: font-size .2s linear;
    -o-transition: font-size .2s linear;
    transition: font-size .2s linear;
}

This technique eliminates any discrepancies in how browsers render the hr element by using simpler div elements. By applying position:absolute to the h1 element, we prevent the animation from affecting other elements on the page. This approach ensures uniform appearance across all browsers.

To improve the hover animation, it is important to adjust the styling properly. Currently, the issue causing the jumping effect is that the display: inline; property is declared within the :hover state instead of in the main element. This results in a shift from the default display: block; of the <h1> tag to display: inline; only upon hovering, leading to the undesirable movement. To fix this, you can consider changing your styling approach as follows:

h1 {
    -webkit-transition: font-size .2s linear;
    -moz-transition: font-size .2s linear;
    -ms-transition: font-size .2s linear;
    -o-transition: font-size .2s linear;
    transition: font-size .2s linear;
}
h1:hover {
    font-size: 3em;
}

This code maintains the default block display of the <h1> tag during the transition. Alternatively, you can try another styling option:

h1 {
    display: inline;
    -webkit-transition: font-size .2s linear;
    -moz-transition: font-size .2s linear;
    -ms-transition: font-size .2s linear;
    -o-transition: font-size .2s linear;
    transition: font-size .2s linear;
}
h1:hover {
    font-size: 3em;
}

With this code, the default block display of the <h1> tag will be changed to inline on hover. Another approach involves removing the default margin to prevent the jumpy behavior while keeping the element as an inline block:

h1 {
    margin: 0;
    -webkit-transition: font-size .2s linear;
    -moz-transition: font-size .2s linear;
    -ms-transition: font-size .2s linear;
    -o-transition: font-size .2s linear;
    transition: font-size .2s linear;
}
h1:hover {
    display: inline;
    font-size: 3em;
}

This code changes the default block display of the <h1> tag to inline on hover, eliminating the margin that causes the jumping effect.
