Unfortunately, this does not work, for every gadget on every blog. Depending upon how a gadget is installed, malicious code may, or may not, be visible - and if visible, may, or may not, be easily removable.
There are three ways to install accessories and gadgets, onto a blog.
- Add into the template, using "Edit HTML".
- Add into an existing HTML gadget, by editing the gadget.
- Add into a new HTML gadget.
The third is preferable, if only to isolate each gadget being added - and make it more easily maintainable.
Add into the template, using "Edit HTML".
For non visible code, the Template Editor will always be the most "logical" installation process.
Many accessories come with installation instructions.
Copy the code here, find the "<Body>" (or "</Body>") tag in your template editor, and paste after (or before) the tag. Then, Save - and test your change.So simple to do, but so easy to mess up. Or have you never had a broken or scrambled template?
And if the code added becomes malicious later, it's can be a pain to use "Edit HTML" when you're stressed (the blog is redirecting, you have angry readers, ...).
Add into an existing HTML gadget, by editing the gadget.
Some people put all of their accessories, of a given type, into one HTML gadget. Maybe the code for each gadget will go into separate cells in a table structure (for visible gadgets), maybe it will simply be separated using "<br />" tags.
Either way, you can identify the problem gadget - when the time comes - but you have to edit the gadget, find the malicious code, delete the malicious code, and Save the gadget. Then, you see if you did not damage the remaining code, that you need to keep?
Oops, I did not mean to delete that tag!
All of this, again, when you're stressed (the blog is redirecting, you have angry readers, ...). Stress == Mistakes, and more stress.
Add into a new HTML gadget.
This takes extra work, in the beginning. You have to add a new HTML gadget, position the new gadget using Layout, make sure that the new gadget does not affect the other gadgets, ...
But extra work, in the beginning, gives less work, when you're stressed.
Just login to Blogger as a blog administrator, click on the link immediately below, then click on "Remove".Isn't that so much easier?
Just be sure to add an HTML gadget, from Basics - and remember to edit the gadget, in HTML mode.
The bottom line.
It's easier, and more logical, to add code directly, using "Edit HTML". And, it keeps the code base more compact.
But if you ever have to remove code, quickly, having each code module isolated as a separate HTML gadget is way, way easier.
You'll find out, one day - if you ignore me, now.
