Google form doesn't display correctly in wordpress website

You need to downgrade your form within Google Drive. See this post and this post on my web site for instructions.

Thanks Mike.

It worked
but it doesn’t look cool enough to show on a website.

May be alignment problem. Please suggest for the same.

That is where Custom CSS comes in. Using Custom CSS you can make the Google Form look like a native part of your web site. There is no generic solution for doing this as every theme is different there for the CSS will be different.

For example, if you add the following CSS, it improves (in my opinion) the look of the form on your web site:

label.ss-q-item-label {
    display: block;
}

input.ss-q-short {
    width: 300px;
}

There is a lot more you can do with CSS to make your form look even better.
