CSS - display: none; not working

Question

I'm trying to develop a mobile stylesheet and in this stylesheet I want to remove a particular div.

In the HTML code of the div, I place an id called "tfl", as shown below:

<div id="tfl" style="display: block; width: 187px; height: 260px; font-family: Verdana, Arial, Helvetica, sans-serif !important; background: url(http://www.tfl.gov.uk/tfl/gettingaround/journeyplanner/banners/images/widget-panel.gif) #fff no-repeat; font-size: 11px; border: 1px solid #103994; border-radius: 4px; box-shadow: 2px 2px 3px 1px #ccc;">
            <div style="display: block; padding: 30px 0 15px 0;">
                <h2 style="color: rgb(36, 66, 102); text-align: center; display: block; font-size: 15px; font-family: arial; border: 0; margin-bottom: 1em; margin-top: 0; font-weight: bold !important; background: 0; padding: 0">Journey Planner</h2>
                <form action="http://journeyplanner.tfl.gov.uk/user/XSLT_TRIP_REQUEST2" id="jpForm" method="post" target="tfl" style="margin: 5px 0 0 0 !important; padding: 0 !important;">
                    <input type="hidden" name="language" value="en" />
                    <!-- in language = english -->
                    <input type="hidden" name="execInst" value="" /><input type="hidden" name="sessionID" value="0" />
                    <!-- to start a new session on JP the sessionID has to be 0 -->
                    <input type="hidden" name="ptOptionsActive" value="-1" />
                    <!-- all pt options are active -->
                    <input type="hidden" name="place_origin" value="London" />
                    <!-- London is a hidden parameter for the origin location -->
                    <input type="hidden" name="place_destination" value="London" /><div style="padding-right: 15px; padding-left: 15px">

                            <option value="locator">Postcode</option>
                            <option value="address">Address</option>
                            <option value="poi">Place of interest</option>
                        </select>
                    </div>
                    <div style="margin-top: 10px; margin-bottom: 4px; padding-right: 15px; padding-left: 15px; padding-bottom: 15px; background: url(http://www.tfl.gov.uk/tfl/gettingaround/journeyplanner/banners/images/panel-separator.gif) no-repeat bottom;">
                        <input type="text" name="name_destination" style="width: 100% !important; padding: 1px" value="232 Kingsbury Road (NW9)" /><select style="width: 155px !important; margin-top: 0 !important;" name="type_destination"><option value="stop">Station or stop</option>
                            <option value="locator">Postcode</option>
                            <option value="address" selected="selected">Address</option>
                            <option value="poi">Place of interest</option>
                        </select>
                    </div>
                    <div style="background: url(http://www.tfl.gov.uk/tfl/gettingaround/journeyplanner/banners/images/panel-separator.gif) no-repeat bottom; padding-bottom: 2px; padding-top: 2px; overflow: hidden; margin-bottom: 8px">

                    </div>
                    <div style="text-align: center;">
                        <input type="submit" title="Leave now" value="Leave now" style="border-style: none; background-color: #157DB9; display: inline-block; padding: 4px 11px; color: #fff; text-decoration: none; border-radius: 3px; border-radius: 3px; border-radius: 3px; box-shadow: 0 1px 3px rgba(0,0,0,0.25); box-shadow: 0 1px 3px rgba(0,0,0,0.25); box-shadow: 0 1px 3px rgba(0,0,0,0.25); text-shadow: 0 -1px 1px rgba(0,0,0,0.25); border-bottom: 1px solid rgba(0,0,0,0.25); position: relative; cursor: pointer; font: bold  13px/1 Arial,Helvetica,sans-serif; text-shadow: 1px 1px 1px rgba(0, 0, 0, 0.4); line-height: 1;" />
                    </div>
                </form>
            </div>
        </div>

This code is not mines as this an embedded code given by the TFL website.

I want to hide this div to make it more friendly for a mobile user, I did:

#tfl {
display: none;
}

This code doesn't work me though, and I even applied to the corresponding header before it and that didn't work, as shown again:

h3.tfl {
display: none;
}

What's the issue here? This code worked on another page on a mapped image. (I can't use jQuery nor JavaScript (uni assingment looking at CSS)).

Answer 1

Remove display: block; in the div #tfl style property

<div id="tfl" style="display: block; width: 187px; height: 260px;

Inline styles take priority over an external CSS file.

Answer 2

This is because the inline style display:block is overriding your CSS. You'll need to either remove this inline style or use:

#tfl {
  display: none !important;
}

This overrides inline styles. Note that using !important is generally not recommended unless it's a last resort.

Answer 3

In the HTML source provided, the element #tfl has an inline style "display:block". Inline style will always override stylesheets styles…

Then, you have some options (while as you said you can't modify the html code nor using javascript):

• force display:none with !important rule (not recommended)

• put the div offscreen with theses rules :

  #tfl {
      position: absolute;
      left: -9999px;
  }
  

Answer 4

Another trick is to use

.class {
position: absolute;
visibility:hidden;
display:none;
}

This is not likely to mess up your flow (because it takes it out of flow) and makes sure that the user can't see it, and then if display:none works later on it will be working. Keep in mind that visibility:hidden may not remove it from screen readers.

Answer 5

Check following html I removed display:block from style

<div id="tfl" style="width: 187px; height: 260px; font-family: Verdana, Arial, Helvetica, sans-serif !important; background: url(http://www.tfl.gov.uk/tfl/gettingaround/journeyplanner/banners/images/widget-panel.gif) #fff no-repeat; font-size: 11px; border: 1px solid #103994; border-radius: 4px; box-shadow: 2px 2px 3px 1px #ccc;">
        <div style="display: block; padding: 30px 0 15px 0;">
