Can someone explain why the createElement function is not maintaining inline-block whitespace between elements?
First rectangle shows normal html string concatenation:
var htmlString = '<div class='inline-block'...></div>'
$(parent).html(htmlString);
The second rectangle displays output using createElement for DOM elements:
var htmlElement = createElement('div');
htmlElement.className('inline-block');
...appendChild(htmlElement);
What causes this difference in output?
Thank you
If you want to create a space between elements, you can achieve this by inserting a textNode between them.
When adding a String to HTML, the string is parsed as HTML which may result in the combination of multiple whitespaces into a single whitespace, generating a textNode by the HTML parser. However, when using createElement, textNodes need to be created manually by the user. Think of it as taking control and responsibility for generating HTML yourself.
var parent = document.getElementById('parent');
var htmlString = document.createElement('div');
htmlString.className= 'inline-block';
var textNode = document.createTextNode(' ');
var htmlString2 = document.createElement('div');
htmlString2.className= 'inline-block';
parent.appendChild(htmlString);
parent.appendChild(textNode);
parent.appendChild(htmlString2);.inline-block {
display: inline-block;
width: 100px;
height: 20px;
border: 1px solid red;
}<div id="parent"></div>\n can also be used for the same purpose, if you were attempting to add a line break.
var parent = document.getElementById('parent');
var htmlString = document.createElement('div');
htmlString.className= 'inline-block';
var textNode = document.createTextNode('\n');
var htmlString2 = document.createElement('div');
htmlString2.className= 'inline-block';
parent.appendChild(htmlString);
parent.appendChild(textNode);
parent.appendChild(htmlString2);.inline-block {
display: inline-block;
width: 100px;
height: 20px;
border: 1px solid red;
