.style attribute, or using the
.className attribute. These two methods provide access to any CSS properties associated with an element.
.style attribute allows developers to directly access the style of an element and change it. This is done by using the syntax
element.style.property = "value". The
.className attribute allows developers to access the class of an element and change it. This is done by using the syntax
element.className = "className". By using these two methods, developers can easily change the style of an element on a webpage.
.style attribute. We could use this code snippet to change the color of text on a web page:
document.getElementById("text-element").style.color = "red";
.className attribute to change an element’s style class:
document.getElementById("text-element").className = "new-style-class";
Here we have obtained an element with an id of “text-element” and then changed its class name to “new-style-class”. This would automatically change any CSS properties associated with that style class.
We can also use the
.setAttribute method to change an element’s style. For example, we could use this code snippet to change the font size of an element:
document.getElementById("text-element").setAttribute("style", "font-size: 20px;");
- Make sure you use correct syntax when writing code; incorrect syntax can result in errors that are difficult to debug.
- Understand how HTML elements are structured; this will make it easier to accurately target specific elements and create meaningful changes.
- Learn how browser caching works; this will help you understand why changes you make may not immediately show up on the webpage.
- Test your code in multiple browsers; different browsers may render pages differently so it is important to test your code in multiple browsers.
