Error: "No skip navigation link is present". You need to insert the following text, right after the <head>
mark in the html page.
<div id="skiptocontent">
<a href="#maincontent">skip to main content</a>
</div>
Than, go to the CSS code and specify the following:
<style type="text/css">
#skiptocontent {
height: 1px;
width: 1px;
position: absolute;
overflow: hidden;
top: -10px;
}
</style>
After that, go to the beginning of the main content of your page (usually the main headding or the first paragraph of text), and add the following code, just before:
<a name="maincontent"></a>
Eror: "Empty Alt attribute"

In order to fix this error you need to go to the HTML portion of the program, and look for the appropriate Input Field (a box). Here is an example:
<select name="unitsystems"></select>
After name="unitsystems" add the following: title="Unit system"
You might have the following:
<Input type="text">
After type="text" add title="Discharge"
Error: "Use h1-h6 to identify headings"
In order to fix that error go to the main headding of the particular web page, and insert
<h1>
at the beggning of heading and </h1>
at the end of the headding. For example:
<h1>
<div align="center" class="heading1"><b>online_culvert: Hydraulic design of highway culverts by FHWA method</b></div>
</h1>
However, if you simply do not have a heading on the page you can just place
<h1></h1>
at any place on the page.

(Ponce, 1989) place (Ponce, 1989: p.154)
or put numbering such as: [1]
