How to set the size of button in HTML - html

Question

I have some buttons on my pure HTML/JS page.
When the page is opened in browser, the button size is normal.
But on refresh/reloading page, the button size is reduced.
In fact, I have not set the button text value. The button's text is blank.
How should I set the size of my button in HTML irrespective to the size of the text?

Answer 1

Do you mean something like this?
HTML
<button class="test"></button>
CSS
.test{
height:200px;
width:200px;
}
If you want to use inline CSS instead of an external stylesheet, see this:
<button style="height:200px;width:200px"></button>

Answer 2

This cannot be done with pure HTML/JS, you will need CSS
CSS:
button {
width: 100%;
height: 100%;
}
Substitute 100% with required size
This can be done in many ways

Answer 3

button {
width:1000px;
}
or even
button {
width:1000px !important
}
If thats what you mean

Answer 4

If using the following HTML:
<button id="submit-button"></button>
Style can be applied through JS using the style object available on an HTMLElement.
To set height and width to 200px of the above example button, this would be the JS:
var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';
I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.
