JavaScript text spacing

I'm currently utilizing the JavaScript code snippet below to clear out the existing content within a div element in order to insert new elements. However, I've encountered an issue where once the div is cleared, its CSS styling is lost. I am attempting to either retain or update the styling:

JavaScript Function

function Changecon() {
    var element = document.getElementById("myList");
    while (element.firstChild) {
        element.removeChild(element.firstChild);
    }        
    document.getElementById("myList").style.lineHeight="577";
};

Unfortunately, the last line of code seems to be ineffective. Any suggestions on how to resolve this? Thank you in advance.

Answer №1

Make sure to include the unit (px) at the end of the value.

document.getElementById("myList").style.lineHeight = "577px";

Answer №2

Consider specifying a unit like px when setting the line height value. Another option is to clear your div by using innerHTML.

To ensure that 577px is the minimum height even when there is no content, set the minHeight property of the element. This is important because line height won't have an impact if there are no lines.

function UpdateContent() {
    var container = document.getElementById("contentContainer");

    container.innerHTML = "";
    container.style.lineHeight = "577px";
    container.style.minHeight = "577px";
}
