Reset Styles for input elements and restyling to b

问题:

I have a simple input field.

<input name="1" onfocus="this.value=''" type="text" size="20" value="input 1" title="Enter your search here" />

Because different browsers add different amounts of padding, margin and border to it, I have to reset it as follows.

input
{
padding: 0;
margin: 0;
border: 0;
border: none;
}

Now I have a unstyled (leaving other properties such as font-size or cursor alone for the movement) and I want to bring back the appearnce that were default before the reset but with consistant values so that the appearance as well as the dimensions are same in all browsers. I do

input
{
border: 1px inset #F0F0F0;
}

However it changes something and the appearnce is not the same as per this fiddle where the first input (input 1) has not been reset with the border property while the second input (input 2) has been reseted (border: 0; border: none;) and again restyled (border: 1px inset #F0F0F0;).

jsFiddle

How do I get the same appearance back after applying a style reset to it.

回答1:

You can't get the default styles back once you change them. If you want to normalize the margins and padding across browsers, just normalize the margins and padding and don't touch any of the other styles, especially border and background.

回答2:

Short answer is change

border: 1px inset #F0F0F0;

to

border: 1px solid #A9A9A9;

Long Answer

I feel there is a better answer to the problem that the OP had in their fiddle.

The problem was with their use of inset instead of solid.

Here is the original js Fiddle code:

input
{
    padding: 0;
    margin: 0;
}

input[name="1"]
{
    margin: 10px;
}

input[name="2"]
{
    border: none;
    border: 0;
    border: 1px inset #F0F0F0;
}

<input name="1" onfocus="this.value=''" type="text" size="20" value="input 1" title="Enter your search here" />
<input name="2" onfocus="this.value=''" type="text" size="20" value="input 2" title="Enter your search here" />

Here is the fix that I believe the OP was looking for:

input
{
    padding: 0;
    margin: 0;
}

input[name="1"]
{
    margin: 10px;
}

input[name="2"]
{
    border: 1px solid #A9A9A9;
}

<input name="1" onfocus="this.value=''" type="text" size="20" value="input 1" title="Enter your search here" />
<input name="2" onfocus="this.value=''" type="text" size="20" value="input 2" title="Enter your search here" />

All I changed was the

input[name="2"]
{
    border: none;
    border: 0;
    border: 1px inset #F0F0F0;
}

to

input[name="2"]
{
    border: 1px solid #A9A9A9;
}

There is no need to set border to none then set it to 0 and then set it to your desired settings. The only reason to do this would to be if there were different fallback options necessary for different browsers. But as far as I know all browsers that should be considered support the basic border property with the shorthand above. As for the actual settings that I changed, the inset gives you that old 3D-ish looking cut in look and the color was too close to the jsFiddle background plus this color looks closer to the default I see in most browsers.
