input text extends outside div

i have a div and im setting the width of the input text to 100% and it extends outside its container. Why?

<div style="background: tomato; margin: auto; width:90%;height:100px;">

        <label class="" for="username" style="display:block;">User Id:</label>
        <input type="text" style="width:100%;margin:0;">

The reason is, that borders don't count to the width of the element so your input will take 100% height + border size (2px in each side by default). To avoid this, you can use CSS3 property box-sizing: border-box; This will make the border part ot the input element, so it will souldn't extend anymore.

However, I recommend you not using inline styles, but having all CSS in external file (in case this wasn't just for illustration purposes)

Let me know if it has helped you. Frank
