Unexpected changes in styles can occur on the page at any moment

I have loaded this CSS:

#ue_email_new{
  border:  1px solid #000000;
}

When the page loads, it displays correctly.

However, when I click on inspect element (using FF 17) and view the CSS, I notice something strange in the debugger:

element {
    border: 1px solid rgb(221, 221, 221);
}

Suddenly, the border changes to this unexpected setting on the actual page.

Where is this coming from?

I have checked my CSS thoroughly but cannot locate these settings. What exactly is the

element

tag that is being referenced by the debugger?

The HTML code looks like this:

<div id="wr_ue_email_new">
  <input autocomplete="off" class="radius_all" name="email" id="ue_email_new" type="text" maxlength="320" />
  <p id="ue_email_lab" class="ue_lab_new">Email</p>
</div>

Answer №1

The element keyword is used to specify inline styles for the element, which take precedence over any CSS rules defined in your stylesheet.

For example, in the Firefox inspector, the CSS:

element {
    border: 1px solid rgb(221, 221, 221);
}

Will result in the following HTML output:

<input style="border: 1px solid rgb(221, 221, 221);" autocomplete="off" class="radius_all" name="email" id="ue_email_new" type="text" maxlength="320" />

Make sure to check your source HTML for any existing inline styles and verify that there is no JavaScript dynamically adding inline styles.

Answer №2

It appears that the code snippet you're observing is likely a result of Firebug displaying the inline styles for the current element. While my version of Firefox/Firebug shows element.style {...} rather than just element, Chrome may display it differently, but the function remains the same.

Based on what you're seeing, it seems like a Javascript event is being triggered, potentially a mouseover event or something similar, which is dynamically setting the CSS border for the element.

When using Firebug to select an element, it temporarily pauses normal event handling on the page until you've made your selection. Once the element is selected, the events resume as usual.

It's possible that the triggering event occurs immediately upon selection, causing the Javascript code related to that event to execute and apply the CSS border styling. This gives the impression that Firebug is modifying the styles, when in reality, it's the event handling logic at play.

This could explain why you couldn't locate the code in your CSS files - it likely resides within your Javascript code instead.

To investigate further, I suggest searching through your JS code for the specific color value mentioned (as @adaam pointed out, the equivalent hex values are #DDDDDD or possibly #DDD).
