<button onclick="updateLayout()">Click here</button>Using getElementsByTagName is not the issue, but here are a couple of things to consider:
px for font size.Refactored code example:
function changeStyling() {
var para = document.getElementsByTagName("p");
para[0].style.fontSize = "25px";
para[1].style.color = "red";
}<p>This is paragraph 0</p>
<p>This is paragraph 1</p>
<p>This is paragraph 2</p>
<p>This is paragraph 3</p>
<button onclick="changeStyling()">click</button>Utilize px to specify font size
function modifyStyle() {
var para = document.getElementsByTagName("p");
para[0].style.color = 'blue';
para[1].style.fontSize = '20px';
}<p>This is paragraph number one</p>
<p>This is paragraph number two</p>
<p>This is paragraph number three</p>
<p>This is paragraph number four</p>
<p>This is paragraph number five</p>
<p>This is paragraph number six</p>
<p>This is paragraph number seven</p>
<button onclick="modifyStyle()">
Click Me
</button>getElementsByTagName is functioning correctly, but remember that the `fontSize` requires a value of type string. Additionally, to apply color, you need to use the CSS property 'color'.
function changeStyling() {
var para = document.getElementsByTagName("p");
para[0].style.fontSize = '25px';
para[1].style.color = "red";
}<p>This is paragraph 1</p>
<p>This is paragraph 2</p>
<p>This is paragraph 3</p>
<p>This is paragraph 4</p>
<p>This is paragraph 5</p>
<p>This is paragraph 6</p>
<p>This is paragraph 7</p>
<button onclick="changeStyling()">
click
</button>function updateDesign() {
var paragraph = document.getElementsByTagName("p");
// console.log(paragraph);
paragraph[0].style.fontSize = '25px';
paragraph[1].style.color = "red";
}<p> asdASDas </p>
<p> asdASDas </p>
<p> asdASDas </p>
<p> asdASDas </p>
<button onclick="updateDesign()"> push me </button>Test out the code, I change the font size to 25 pixels and the color to red.
Your styling is incorrect
para[0].style.fontSize = "25px"; // setting font size to 25px
para[1].style.color = "red"; // changing color instead of font size
