one way is add style to p tag

p{

margin : 0!important

}

another way is remove empty p tag

you have to apply border-radius:

.submit {
  border-radius: 25px;
}

If you're trying to apply background images to html and body that fill up the entire browser window, neither. Use this instead:

html{ height : 100%;} body{min-height : 100%;}

the reason why you have to specify height and min-height to html and body respectively is because neither element has any intrinsic height. Both are height: auto by default. It is the viewport that has 100% height, so height: 100% is taken from the viewport, then applied to body as a minimum to allow for scrolling of content.

universal selector apply style to all element so if you have another tag except h1,h2,h3  you must be  apply style to parent class 

i think you need to add double quotes arround function name

<button onclick = "someFunction()" >button</button>

                <td colspan="5">1</td>
            </tr>
            <tr>
                <td colspan="3">2</td>
                <td colspan="2" rowspan="3">3</td>
            </tr>
            <tr>
                <td rowspan="3">4</td>
                <td colspan="2">5</td>
            </tr>
            <tr>
                <td rowspan="2">8</td>
                <td rowspan="2">9</td>
            </tr>
            <tr>
                <td>6</td>
                <td>7</td>
            </tr>
        </table>

  if (x.style.display === "none") {
    x.style.display = "block";
  } else {
    x.style.display = "none";

< div onkeyup="thenameofthefunction()" onclick="thenameofthefunction()">click</div>
